Abstract: Lock having a latch (1) which can be displaced between an open position and a closed position and is retained in the closed position by a catch (2), it being possible for the catch (2), by a release member (3) being pivoted about a pivot bearing, to be moved from a blocking position into a release position which allows the latch to be displaced into its open position, the release means (3) acting on the catch (2), and having a safety member (4) which can assume an active position, which allows displacement of the catch (2) by release member actuation, and a safety position, which allows the release member to be inoperative upon actuation, the changeover between the active position and the safety position of the safety member (4) taking place, in particular, by an electric motor such that with the release member (3) moved into the release position, upon changeover from the safety position into the active position, the catch (2) is moved into its release position, wherein a safety lever (5) which carries the sa

Abstract: Motor-vehicle door lock (1) which can be actuated by means of an interior handle and an exterior handle, wherein the exterior handle acts on a trigger (15), actuation of which triggers a catch (9) to retain a rotary latch (10) in an unlocked position of the lock, and is inactive in a locked position and in a safeguarding position. The interior handle (30) acts on a transmission lever (14) which triggers the catch (9) in the unlocked position and the locked position, and is inactive in the safeguarding position. The transmission lever (14) has a switching member (26) wherein in the locked position, initial actuation of the interior handle (30) switches over the switching member (26) from the inoperative position into the operative position, and switches over the lock (1) into the unlocked position.

Abstract: The invention relates to a lock with a latch (32), held in the closed position by means of a detent pawl (36). A tripping device (39) co-operates with the detent pawl (36) and with a safety element (43, 51, 54), which can adopt a working position, permitting a displacement of the detent pawl (36), by a tripping action and a safety position, permitting an idle operation of the tripping device on operation thereof, whereby on switching between the working and the safety position, with a tripping device (39) in the release position thereof, the detent pawl (36) is moved to the released position thereof. The pivot bearing (S) for the tripping device is non-active in the safety position in order to improve the force transmission and the control.

A holder housing is rigidly connected to an other door installation member. The door holding rod extends through the holder housing. A first roller is mounted in the holder housing so as to be rotatable about a rigid axis. A second roller is rotatably mounted on a load-applying arm of a torsion rod spring which rests against the holder housing. The door holding rod extends between the two rollers. The door holding rod has over its entire length which comes into contact with the rollers a rounded cross-sectional shape and the locking portions are formed by at least one bent portion of the door holding rod directed transversely of the longitudinal axis of the door holding rod.

Abstract: A seat for use in a motor vehicle has a body supporting unit and a back rest which is pivotably connected to the body supporting unit by two hinges having pintles provided with eccentrics which cause the back rest to perform a composite pivotal and transverse movement while it changes its orientation with reference to the body supporting unit. The back rest carries two pivotably mounted arm rests which are connected to the back rest and to the body supporting unit by linkages serving to ensure that the orientation of the arm rests remains substantially or completely unchanged while the back rest is pivoted with reference to the body supporting unit. A second linkage can be used to pivot the front ends of the arm rests rearwardly and upwardly when the back rest is lifted with reference to the body supporting unit and is pivoted forwardly toward the dashboard in a two-door motor vehicle in order to afford convenient access to the rear seats or to permit a passenger to leave a rear seat with a minimum of effort.

Abstract: A hinge joint wherein a first component is affixed to the body supporting portion and a second component is affixed to the back rest of a seat, particularly in a motor vehicle. The two components are articulately connected to each other by a pintle having a cylindrical portion journalled in a sleeve of the second component, and an eccentric conical portion journalled in a complementary hole of a spur gear forming part of the first component. A spring biases the conical portion into the hole, and the conical portion has an eccentric recess for a cylindrical portion of the sleeve. Such design of the pintle contributes to simplicity and to a reduction of space requirements of the hinge joint. The conical portion can move the spur gear of the first component radially relative to an internal gear of the second component when the pintle is rotated by a hand wheel or by a motor.

Abstract: A hinge joint which pivotably connects the back to the weight carrying portion of a seat in a motor vehicle has a shaft with two concentric and two eccentric cylindrical portions. The component which is attached to the back has an internal gear mating with a spur gear of the component which is attached to the weight carrying portion of the seat. One of the components is rotatably mounted on the concentric cylindrical portions of the shaft, and the other component surrounds with a small clearance one of the eccentric cylindrical portions. The other eccentric cylindrical portion is surrounded by the prong-like segments of a diaphragm spring or by discrete segments to compensate for radial clearance between the mating teeth of the gears on the two components.

Abstract: A hinge joint wherein one of the leaves is secured to a fixed part and the other leaf is secured to the pivotable back rest of a seat in motor vehicle and is pivotable with reference to the fixed leaf about the axis of a pintle which can be rotated by a hand wheel or a motor. The other leaf carries a braking member with a cylindrical or frustoconical internal surface which is engaged by the peripheral surface of a prestressed elastic split ring defining a gap for the projection of a blocking element which is affixed to the pintle and urges the split ring into stronger frictional engagement with the braking member when the back rest is acted upon to pivot the other leaf. A coupling device is secured to the hand wheel or to the motor to disengage the split ring from the braking member when the pintle is rotated by the hand wheel or by the motor. The end portions of the split ring flank the projection of the blocking element and are flanked by two protuberances of the coupling device.

Abstract: The present invention relates to an adjusting device for vehicle seats having a threaded spindle (4) and a spindle nut arranged thereon, each of which is connected in an axially immovable manner with one or the other of elements (1, 2) to be adjusted relative to each other. The spindle nut (13) is provided with a full-length (or continuous) channel (20) running parallel to the threaded bore which receives the threaded spindle (4), which channel receives a bar (22) which prevents a rotation of the spindle nut (13) about the longitudinal axis of its threaded bore. The opposing boundary surfaces (21) of the channel (20), which cooperate with the bar (22) are spaced from each other such that at the midpoint of the channel (20) the space is equal to the bar thickness and uniformly increases toward the two ends of the channel.

Abstract: An arrangement for adjustment of seats has a seat support which is connected with rails associated with a vehicle bottom. The front end region of each lateral support member is connected via a swinging member with the associated rail in a pivotable manner. Each swinging member has a toothed rack in which a pinion supported in each lateral support member engages, and the pinion is arranged on a shaft extending through the lateral support members. An actuatable locking device fixes the pinion in the toothed rack together with the seat support in selected positions in stepped manner. For lifting or lowering the front and the rear seat region independently of each other, or together with each other, the rear end region of each lateral support member is also supported on a shaft extending through the seat support and fixedly connected with a pinion associated with each lateral support member.
