摘要:
There is provided a joint fitting of a backrest for a motor vehicle seat, which has a first part of a joint, which is arranged at a seat frame (22) and a second part of a joint, which is arranged at a back of the seat (24), whereby both parts of the joint are adjustable towards each other via an adjustment device, for the reason of which one axis (32) of one part of the joint protrudes into a recess of the other part of the joint, the recess is a long hole (30), within which the axis (32) is guided on a dictated path.

The present invention teaches a wobble-hinged metal fitting suitable for adjustable motor vehicle seats, and more particularly, for back seat gears. The fitting includes two hinged brackets connected together by an eccentric, a carrier and shaft running therethrough. Each bracket contains an internal gear and an external gear associated with the internal gear. The eccentric is positioned next to one of the gears and is turnably connected to the shaft. The eccentric includes means for compensating play in the seat which consist of an eccentric part having a receiving inlet, at least one rolling body, at least two jamming planes and at least one spring. The spring is positioned such that it pressures the rolling body to come in contact with the jamming plane on one side and the gear on the other side. The carrier is positioned such that when the rolling body is in a locked position, an initial turning movement of the shaft results in the release of the locked rolling body before the eccentric starts to move.

The invention relates to a longitudinal guide for a motor vehicle seat with a pair of carries comprising a seat carrier and a sliding bottom carrier, which are movable towards each other in their longitudinal direction and which are in contact with each other by means of sliding devices and/or rollers, whereby each carrier a) possesses at least two guide areas and each guide area of one carrier is adapted in a form to the related guide area of the other carrier in such a way that sliding devices and/or rollers are each taken up between two guide areas of different carries and b) possesses at least one area of gearing, which is modelled in such a way that it does not come into contact with at least one area of gearing of the corresponding other carrier under normal circumstances, but comes into contact, if the two carriers are separated from each other, and obstructs such a separation by means of gearing. For the manufacture of sectional areas of the longitudinal guide which determine the statics, two different kinds of material are used, preferably steel and light metal.
摘要:
A motor vehicle seat with a longitudinal guide that has a locking device. The seat has a backrest which has a release lever for tilting the seat forward. The operation of the release lever releases the backrest from a normally upright position and allows it to be tipped forward. The backrest is connected to the locking device of the longitudinal guide by means of a release mechanism so that when backrest is tipped forward, the locking device can be released and the motor vehicle seat can be moved manually in the longitudinal guide. Alternatively, if the backrest is in the upright position, the locking device is either ready to be operated, or in the process of operating. A memory device is provided for finding a position where the locking device was previously engaged following the longitudinal movement of the seat along the guide.

The back-rest hinge is intended for a vehicle seat with a seat support (20) and a back-rest, which is hinged to this support by means of a swivel joint (shaft 28), and a locking mechanism (44 to 58) for adjusting the angle of inclination of the back-rest (30) in relation to the seat support (20). A locking lever is hinged to the back-rest at a hinge point which is at a distance from the swivel joint along the lengthwise direction of the back-rest (30). The locking lever (38) has a locking area which extends in the direction of the seat support (20) and toward a front edge of this seat support. On the seat support (20) an interlock assembly is provided which interacts with the locking area, can be released, and is normally in mesh (locking lever 52), and with which an activating member is associated (activation lever 56).

A longitudinal guide for a seat sliding device for vehicle seats includes two elongated tracks that slide relative to each other. A guide is arranged between the tracks, there being at least two guides when viewed from the profile of the longitudinal guide, of which at least one is constructed using roller bodies. One track embraces the other track. The tracks are interconnected so that they will not separate. The tracks are positioned in an adjoined, preloaded manner. The tracks are manufactured of steel sheet containing at least 0.35% carbon content and are heat treated after they are complete.

The vertical and angular position adjusting device includes at each lateral side of the seat a five-bar linkage including an underframe, a seat carrier bar, a pair of two-arm support levers pivotably connected to the frame, a coupling bar linked between the outer arm of one of the support levers and an end portion of the carrier bar, and the other end portion of the carrier bar being hinged to the outer arm of the other support lever. The support levers at one lateral side of the seat have gear segments formed on the inner arm of each support lever. A pair of arresting levers is linked to the underframe between the support levers and is provided with arresting teeth engageable with respective gear segments. A pair of switching levers is linked to the underframe between the arresting levers and is spring-biased to abut against a front locking surface provided on each arresting lever in order to hold the latter in a locking position. A control lever is linked to the underframe between the switching levers and supports a cam which displaces the switching levers against the force of the spring into a released position in which the selected arresting lever is disengaged from the support lever.

A lockable guide assembly for adjustable vehicle seats comprising a pair of parallel guided rails attached to the vehicle seat; a pair of parallel guiding rails slidably arranged with respect to the guided rails and attached to the vehicle floor. Each of the rails is formed with a high-webbed U-shaped cross-section with inner and outer arms substantially overlapping with the arms of the U-shaped section of the other rail, the height of each section being about twice its width. The inner arm on each rail extends into the U-shaped portion of the other rail occupying nearly the full depth of the U-shaped portion leaving only a small gap between the free end of the inner arm and the inside surface of the U-shaped portion of the outer arm. The outer arms are wider or deeper than the inner arms and extending beyond the depths of the inner arms, and the outer circumference of the U-shaped portion of the guided rails is straddled by the arms of the guiding rail.

An arrangement for arresting a seat of a vehicle includes an elongated stationary element which is provided with a row of separate recesses being arranged on the element so as to correspond to a plurality of possible positions of the seat. At least two blocking elements are provided for joint movement to a rest position in which the seat is free to move lengthwise of the row of recesses; each of the blocking elements is movable independently of the other from the rest position to an arresting position in which the blocking elements are inserted in respective recesses independently of one another to thereby prevent further movement of the seat.

A motor vehicle seat includes a longitudinal guide with a locking mechanism with a release device for locking and unlocking the locking mechanism in an engaged and in an unengaged position to allow movement of the seat. The backrest can be tipped forward and is connected to the locking mechanism. The locking mechanism unlocks when the backrest is tipped forward and for allowing manual movement of the motor vehicle seat in a longitudinal direction. A memory device serves to find the previously engaged position of the locking mechanism.
