  • Publication number: 20200355292
    Abstract: A valve drive with a snap function includes a rotary drive input, a lead screw connected to or formed by the rotary drive input, a slide in threaded engagement with the lead screw to form a screw thread, the slide being mechanically connected or connectable to a valve body and being movable in the direction of a longitudinal axis. A bearing housing is provided in which the lead screw is mounted so as to be rotatable about the longitudinal axis and stationary in the direction of the longitudinal axis. The bearing housing is held against a displacement along the longitudinal axis by a releasable locking device, countering the preload force of a snap spring.

  • Patent number: 5044575
    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.

  • Patent number: 5029369
    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.

  • Patent number: 4948171
    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.
