Abstract:
A vehicle seat track assembly (10) includes an elongated fixed track structure (12) constructed and arranged to be fixed to a vehicle floor and movable track structure (14) cooperable with the fixed track structure (12). A plurality of rolling elements (16) are engaged between track structures for rollingly supporting the movable track structure (14) on the fixed track structure (12) to enable the movable track structure (14) to be moved in opposite directions through a range of adjusting movements with respect to the fixed track structure (12). An adjusting mechanism (40) is operatively associated with the track structures and is constructed and arranged to permit the movable track structure (14) to be moved through the adjusting movements. The adjusting mechanism (40) includes a locking and releasing device (42) constructed and arranged to be moved between (A) a locking position preventing the adjusting movements from being affected and (B) a releasing position wherein the locking and releasing device (42) is operable to release the adjusting mechanism (40) to permit the adjusting movements. A lock and release system (58) is operatively associated with the track structures and includes locking structure (89) movable between a released position permitting the adjusting movements and a locked position preventing the adjusting movements from being affected. The lock and release system (58) includes shock responsive structure (60) constructed and arranged to move the locking structure (89) to the locked position thereof in response to a crash condition which occurs while the locking and releasing device (42) is in the releasing position thereof.
Abstract:
A sliding seat mechanism for a vehicle seat comprises transversely spaced fixed floor runners (10, 12) within which slide co-operating seat runners (14, 16) fixed to the underneath of the seat. Respective pivotally mounted latches (22, 40) are carried by the seat runners (14, 16) for latching engagement within apertures in respective floor runners (10, 12). The latches are movable from their latched to their unlatched positions by means of respective release levers (58, 60) which are themselves biased to an inoperative position in which the latch members are movable from their unlatched to their latched positions independent of the release levers.
Abstract:
An auxiliary release device for a seat assembly is disclosed providing a release device which is operated by an activator located in a readily accessible position for the operator. The release device includes a hydraulic power supply for activating the mechanical release lever to enable fore and aft adjustment of the seat.
Abstract:
In an adjustable rail assembly for motor vehicle seats and the like the slide rail (51) and the guide rail (55) are moveable longitudinaly with respect to each other into any one of a number of predetermined positions. To retain them in the chosen position releasable locking means in the form of a pawl (53a, 53b) and ratchet (41, 42) mechanism is provided.
Abstract:
A lock apparatus (10) selectively locks and unlocks a rotatable shaft (12) from rotation. A brake disc (20) is formed with opposed lock surfaces (32, 34). First and second lock rings (100, 102) rotatably mounted on first and second bearing members (54, 56) are alternatingly moved by rotation along spaced projections on the adjacent first and second bearing members (54, 56) into locking engagement with the lock surfaces (32, 34) on the brake disc (20) and away from the brake disc (20) to an unlocked position. An outer member (58) of each of the bearing members (54, 56) is held in a fixed position by engagement with first and second end caps (40, 124) mounted on the brake disc (20). An inner bearing member (60) is axially movable with respect to the outer bearing member (58) to bring bearings (62) disposed in outer and inner races (74, 88) on the outer and inner bearing members (58, 60) into contact with thrust faces (75, 89) on the outer and inner members (58, 60) as axial force is imposed on the rotatable shaft (12) to enable rotation of the shaft (12).
Abstract:
The invention concerns a locking device for vehicle seats, in particular motor vehicle seats, said device having a row of detent openings (2) and a plurality of spring-loaded bolts (5) which are disposed one behind the other in the direction of this row and which can engage independently of one another in the detent openings (2). At least two of these bolts (5) can engage in one of the detent openings (2) and lock the parts without play in both adjusting directions, in any position within the adjusting range of these parts which are to be locked and can be continuously adjusted relative to one another. In addition to its movability enabling it to engage in one of the detent openings (2), each bolt (5) has at least one component part which is movable, the flat area provided for play-free abutment on the delimiting surface of this detent opening (2) being brought into abutment with the delimiting surface without altering the depth of penetration of the bolt (5) in the detent opening (2).
Abstract:
A mounting mechanism for a seat, comprising slide means providing for sliding movement of the seat relative to a support therefor; latch means for retaining the seat in a selected one of a number of positions in its range of said sliding movement; and means for retaining an indication of said selected seat position to enable the seat to be moved from said selected position and returned thereto.
Abstract:
In a locking device for vehicle seats, especially motor vehicle seats, with two mutually and steplessly movable parts, to one of which is allocated a rail (1) extending in the adjustment direction with a row of catch apertures (6) along the rail while the other has locking teeth (2-5) of which at least one engages in one of the catch apertures (6) in each position of the mutually adjustable parts, the extent of which along the rail is greater than the size of each locking tooth in that direction, the clear width of the catch apertures (6) transversely to the rail continuously changes along the rail. The surfaces bearing upon one another without clearance in the locking direction in the locked position are formed by at least one of the two longitudinal sides (6') defining the clear width of the catch apertures (6) and at least one of the two locking tooth limiting surfaces (8) facing these two longitudinal sides (6).
