The invention relates to a fitting (10) for a vehicle seat, in particular for a motor vehicle seat, comprising a first fitting part (11) and a second fitting part (12) which can be rotated with respect to each other, a clip ring (13) which is fixed to the first fitting part (11) for holding both fitting parts (11, 12) axially together by means of an outer ring section (13b) and engaging the second fitting part (12) by means of an inner annular section (13a), and stops (13g, 15) which define the limits of the relative rotation of both fitting parts (11, 12) and which comprise at least one limiting stop (13g) embodied as a clip ring (13) and at least one locking stop (15) which is joined to the second fitting part (12) such that the limiting stop (13g) protrudes outwards from outside of the annular section (13b) of the clip ring (13) and the limiting stop (15) is provided on a structural part secured to the second fitting part (12).

Fitting for a vehicle seat

A seat slide apparatus for a vehicle includes a lower rail, formed into a longitudinal shape and adapted to be fixed to a vehicle floor, an upper rail adapted to be fixed to a seat frame, and assembled to the lower rail to be relatively movable in a longitudinal direction of the lower rail, and a detachment prevention mechanism including an elongated hole, which is formed at the bottom wall portion to open therethrough and which extends in the longitudinal direction, and a load receiving member whose upper end portion is fixed to the upper wall portion and whose lower end portion is inserted downwardly through the elongated hole so as to be movable in an extending direction of the elongated hole, and is engageable with the bottom wall portion in the vicinity of the elongated hole to restrict a movement of the upper rail in an upper direction.

A power seat slide device comprises a lower rail; an upper rail slidably engaged with the lower rail; an elongate threaded bolt member rotatably carried by the upper rail through first and second supporting members; a nut member connected to the lower and rail and meshed with the bolt member so that rotation of the bolt member about its axis induces a longitudinal movement of the upper rail relative to the lower rail; an electric power device for rotating the bolt member with an aid of electric power; a front shock absorbing member slidably mounted on the bolt member between the first supporting member and the nut member; and a rear shock absorbing member slidably mounted on the bolt member between the second supporting member and the nut member. When the upper rail moves to its rearmost position relative to the lower rail, the front shock absorbing member is compressed by the first supporting member and the nut member, and when the upper rail moves to its frontmost position relative to the lower rail, the rear shock absorbing member is compressed by the second supporting member and the nut member.

Power seat slide device

A spindle or worm drive for adjusting devices, especially seat adjustment devices, window lifters and sliding roofs, in motor vehicles. The drive includes a fixed spindle or relatively fixed toothed rack which is secured to the second of the two parts. The gear elements are mounted in a housing which includes at least two plates that can be secured to each other by plug-in connectors. The connectors are also configured as supporting joints that absorb the forces of the gear.

Spindle or worm drive for adjusting devices in motor vehicles

A longitudinal adjuster ( 3 ) for a vehicle seat ( 1 ), particularly a motor vehicle seat, has at least one first seat track ( 5 ) having catches ( 20 ) disposed in at least one row running in the longitudinal axis (x) of the seat. Each catch ( 20 ) includes a front flank ( 21 a ) and a rear flank ( 21 a ) in the longitudinal axis (x) of the seat, and at least one second seat track ( 8 ) that can be displaced relative to the first seat track ( 5 ) in the longitudinal axis (x) of the seat and locked to the same and at least two catch plates ( 12 ) for locking the first seat track ( 5 ) to the second seat track ( 8 ). The catch plates ( 12 ) are displaceably supported in the locking direction (z) in the second seat track ( 8 ) and comprise teeth ( 12 b ) for engaging in the catches ( 20 ) of the first seat track ( 5 ). Each tooth ( 12 b ) includes a front and a rear tooth flank ( 12 d ) in the longitudinal axis (x) of the seat. Each of the catch plates ( 12 ) includes exactly two teeth ( 12 b ) per associated row of catches ( 20 ). Two teeth ( 12 b ) belonging to different catch plates ( 12 ) act together with the row of catches ( 20 ) associated with said teeth ( 12 b ) for locking the first seat track ( 5 ) to the second seat track ( 8 ) with no clearance.

A power seat slide device for an automobile seat includes upper and lower guide rails and a nut and screw assembly for relative slidable movement between the upper and lower guide rails. Rollers are disposed in the lower guide rails and rotatably supported between the upper and lower guide rails. The power seat slide device further includes shoes or balls between the engagement portions provided on each of the upper and lower guide rails.

A seat slide mechanism for vehicles includes a screw member extending longitudinally within an interior portion of the upper rail and a nut member engaging with the screw member. The nut member extends downwardly between the opposed walls of the upper rail to the base of the lower rail to form separated spaces at the both sides of the nut member and between laterally elongated slide members of the upper rail and the base portion of the lower rail. These separated spaces are helpful in arranging the rollers without any interference with the nut member or the screw member.

Seat slide mechanism for vehicles

A seat sliding device is comprised of a pair of laterally spaced lower rails for mounting on a vehicle body floor, each of the lower rails including a channel, a pair of upper rails adapted to carry a seat cushion, each of the upper rails being slidably mounted at an engaging portion to the corresponding lower rail, each of the upper rails having a channel which is positioned above the engaging portion, a screw shaft accommodated in one of the channels, a nut member screwing onto the screw shaft and secured to one of the upper and lower rails, and bearing member supporting rotatably the screw shaft and elastically fit within the channel of the other of the upper and lower rails.

Seat sliding device for vehicle

A sliding device for moving a seat in the lengthwise direction of a vehicle body is comprised of an upper rail having an inner space and supporting the seat, a lower rail having an inner space, secured to a floor of the vehicle floor and mounting the upper rail in such a manner that the upper and lower rails are inter-locked with each other, the upper rail is slidable along the lower rail and the inner space of the upper rail is positioned above the inter-locked portion, a screw shaft rotatably supported by the upper rail and located therein, a nut threadably mounted on the screw shaft and secured to the lower rail so as to be located in the inner space of the upper rail, and a motor for rotating the screw shaft.

Vehicle seat sliding device

A seat slide assembly includes a rail mechanism for slidably supporting a seat on a floor fixedly connected to the floor, an actuating means fixed connected to the rail mechanism through a bracket for actuating the rail mechanism, a bolt member fixed to the rail mechanism by welding and supporting on the bracket, a nut member for fixing the rail mechanism to the bracket by screwing with the bolt member, a groove formed on the nut member, a flange portion formed on the rail mechanism for supporting the nut member, and a projecting portion formed on the flange portion and fixedly inserted into the groove.
