Abstract: An inertial reel assembly for use with a safety belt. The reel assembly includes a spindle portion rotatably mounted within a housing for take up and pay out of the safety belt. The spindle is formed with plurality of teeth which engage and lock with the plurality of teeth formed within the interior of the housing. The spindle is mounted to move along an arc passing through its center point so that the spindle teeth may lock with the housing teeth. The housing teeth may include a flat section formed at the tips of the housing teeth for preventing the engagement of the spindle teeth with corresponding housing teeth when the spindle teeth are angularly misaligned with respect to the housing teeth.

Abstract: A coupling for securing together a pair of members includes a spigot on one member which can be located in a bore in the other member. An angularly adjustable member is located in a transverse bore in the member and defines a thrust surface engageable with a thrust surface on the spigot to draw radially extending thrust faces on the two members into firm axial engagement. The spigot and the bore also define spaced annular cylindrical locating surfaces which provide radial location of the pair of members.

Abstract: A belt clamping apparatus is provided for a seat belt system comprising a belt retractor and a device which is controlled by at least one acceleration sensor and serves to lock gears which are connected to the reel shaft of the belt retractor. The clamping apparatus comprises a clamping wedge, which is guided on a sliding surface that is fixed to a housing to move parallel to a back-pressure plate which is fixed to the housing, and together with the clamping wedge defines a gap for the passage of the belt, and an actuating member, which is movable by the locking device and displaces the clamping wedge to its clamping position. The actuating member is rotatably connected at one end to the housing and is pivoted at its other end to the clamping wedge, when the belt is being extracted further after the gears have been blocked by the actuating member in response to the movement of the reel shaft and imparts a translational movement to the clamping wedge.

Abstract: The tongue at the free end of a safety belt in a motor vehicle is releasably connected to the buckle by a coupling member which can be disengaged from the tongue by a reciprocable release member. The latter can be depressed by hand to thereby pivot (either entirely or in part) prior to completing a translatory movement which results in disengagement of the coupling member from the tongue. If the buckle is abruptly accelerated during an accident, the release member tends to carry out the translatory movement without a preceding pivotal movement whereby a stationary blocking element intercepts a blocking element on the release member and holds the latter against movement to a position in which the coupling member is caused or permitted to release the tongue. Alternatively, the release member is mounted for translatory movement to thereby disengage the coupling member from the tongue.

Abstract: The frame of the motor vehicle carries a vertical rail defining an elongated track for a plastic slide which carries a first pivotable lever serving as a means for releasably coupling the slide to the rail. A pivot member which secures the first lever to the slide carries a deflector for the shoulder belt of the occupant restraint system, and the first lever has a tooth which is biased against one of two sidewalls of the rail to enter into one of a row of sockets in the one sidewall. A second lever or a wheel is provided to extract the tooth from a selected socket and to thus enable the slide to move along the track to a different position in which the tooth is aligned with a different socket. The first lever is centered between the two sidewalls which flank the track for the slide. The central portion of the first lever resembles or constitutes a disc with two convex surfaces which are closely adjacent the respective sidewalls and have centers of curvature on or close the pivot axis of the first lever.

Abstract: An acceleration sensor for vehicle-sensitive systems is mounted on a part connected to the vehicle and comprises a mounting part having a baseplate, which has a spherical socket-shaped recess and bearing means for an impulse lever, which between the tip thereof and the part thereof mounted in the bearing means is enlarged to form a spherical socket-shaped cap. A ball which constitutes an inertia mass is provided between the cap and the socket-shaped recess and an actuating member, which preferably consists of a control pawl which is in contact, or almost in contact, with the tip of the impulse lever and is activated by the tip thereof as the ball is moved out of its position of rest by accelerations having predetermined values. The mounting part is directly or indirectly pivoted to a pivoted part of the vehicle, such as a seat or the rest of a seat, on an axis which extends through the region in which the tip of the impulse lever contacts the actuating member.

Abstract: An acceleration sensor for safety systems such as seat belt systems in motor vehicles, particularly so-called buckle-connected tighteners, comprises a sensor mass which is generally held in a position of rest but is capable of displacement in response to a predetermined critical acceleration to activate the safety system. In one embodiment, an inertial force sensor consists of a sensor lever pivoted to a part fixed in the vehicle, said sensor lever carries at its upwardly protruding free end an inertial mass, preferably in the form of an enlarged head, the sensor lever being held by a spring which urges said sensor lever toward its vertical stand-by position, and being connected by levers and/or links to a release mechanism for releasing a spring-loaded tie rod or the like or a blocking device.

Abstract: In a device for coupling and locking a bracket, which is provided with a buckle of a seat belt, in case of danger to a retaining member, which is fixed in a vehicle, the bracket, or a housing part or the like which is connected to the bracket, is connected to a movable coupling member, which in a guide of a seat frame plate or the like is guided in such a manner or by a linkage is so connected to said seat frame plate or the like that a tension exerted on the buckle will cause the latter to be coupled to the retaining member, which is fixedly mounted in the vehicle.

Abstract: A belt tightener for seat belts in vehicles comprises a device for moving the belt buckle in a belt-tightening sense and for locking the belt buckle at the end of the tightening movement, which device is activated by a so-called vehicle-sensitive system in response to an acceleration or deceleration in excess of predetermined critical values.

Abstract: In a webbing sensitive sensor, a rotatably mounted sensing pawl (14) is provided on a peripheral control cam surface (24) of a rotatable inertia mass (13) and is pressed by this surface into engagement with an internal tooth region. This peripheral control cam surface (24) has from a predetermined point an outwardly falling characteristic for reducing the torque exerted by the pawl on the inertia mass, so that the engagement motion between the pawl and the internal tooth region is effective independently of manufacturing tolerances.

Abstract: In the deflection clamping device according to the invention, a control lever (30) acts via a sloped active surface (56) on a movable clamping member represented by a clamping wedge (48) in such a way, that when activation takes place in the direction of motion of the belt, the clamping wedge has a velocity component that is equal to the belt speed at that moment, so that no relative movement in the vertical direction of motion results between the movable clamping wedge and the belt. This is achieved by having a deflection clamping device with a small structural depth and by having low loading forces on the control lever.

Abstract: In a safety-belt system comprising a winding and locking mechanism, a clamping device is provided which carries out a clamping of the safety-belt outside the reel winding, wherein this clamping effect is caused by a lifting motion of the winding and locking mechanism or of a part thereof and is fastened by suitable means so that the load-bearing clamping organ comes to engage with its entire clamping surface on the belt and the approach of the clamping surface to the belt is synchronized. According to the invention clamping readiness of the clamping organ is begun on every vehicle deceleration of more than 0.45 g and on every belt withdrawal acceleration of more than 1.5 g. The belt winder contains, apart from the driving spring and the winding shaft, only the sensor and control mechanism, and does not require any separate locking elements in order to cause preblocking.

Abstract: The invention relates to a deflection device with means for direct clamping locking of the belt which takes place according to the severity of the loading in a progressive manner. With the usually occurring locking in normal vehicle conditions, such as for example upon braking above 0.4 g, a first arresting action takes place with a weak clamping which does not damage the textile webbing. Only in the case of higher loading, which occurs in the case of an accident, a second arresting action occurs which effects secure and slip-free load transfer by application of aggressive clamping means. This type of locking is--excluding taut belts--the most efficient. It results in very small initial displacement of the occupant. The use-cost analysis is optimal since light and economic winders can be employed.

Abstract: An emergency locking retractor for a vehicle safety belt has a spool rotatably mounted on a frame, primary locking means arranged to block rotation of the spool relative to the frame and secondary locking means for actuating the primary locking means. The secondary locking means including an inertia sensor and a pawl pivotally mounted on a carrier which is movable relative to the frame, the pawl being movable by the inertia sensor into simultaneous engagement with a stop member on the carrier and a ratchet wheel coupled to the spool so that subsequent rotation of the spool of the belt protraction direction causes movement of the carrier which in turn actuates the primary locking means. The stop member is so positioned relative to the pivotal mounting thereof that the pawl comes into abutment with the stop member before its pawl tip abuts against the periphery of the ratchet wheel between adjacent teeth thereof.

Abstract: A seat belt tensioning system for a motor vehicle comprises a locking retractor for a seat belt and a pre-tensioning device for pre-tensioning the seat belt, the pre-tensioning device comprising mounting means for mounting the retractor on a fixed mounting member, the mounting means permitting movement of the retractor in a direction opposite to the protraction direction of the belt. Such movement of the retractor may be caused by a cable coupled to the front bumper of the vehicle.

Abstract: Apparatus for tensioning a strap of a vehicle safety belt system, comprises a cylindrical drum, a first roller journaled on a stationary axis parallel to that of the drum and spaced radially outwardly from the surface thereof, a second roller mounted with its axis parallel to the axis of the drum at a radius between that of the surface of the drum and the first roller, and pyrotechnically powered means for causing angular movement of the second roller about the axis of the drum. Guide means are located at a greater radial distance from the axis of the drum than the second roller and oriented so that, prior to detonation of the pyrotechnic charge, the angular position of the second roller about the axis of the drum is between the first roller and the additional guide means. The strap passes between the second roller and the surface of the drum but radially outwardly of the first roller. Prior to detonation of the pyrotechnic charge, the strap does not touch the surface of the drum.

Abstract: The main locking mechanism of an emergency locking retractor comprises teeth on the flanges of the spool on which the belt is wound, the spool being mounted in bearings arranged to permit limited translational movement in a direction perpendicular to the axis of rotation, between a position in which said teeth formations engage with complementary teeth on the frame of the retractor. Actuating means which are arranged to cause movement of the spool into its engaged position, comprise a ratchet wheel mounted on the spool for rotation and translational movement therewith, a pivotally mounted control member and a pawl which can be moved by a ball-in-saucer sensor into a position in which it couples the control member to the ratchet wheel, so that angular movement of the ratchet wheel in the belt unwinding direction causes angular movement of the control member about a pivot, thus moving the spool so as to bring the teeth on the flanges into locking engagement with the teeth on the frame.
