A power supply mechanism for a long-stroke seat has a wire harness accommodation box having at least one accommodation space and at least one opening; a drag chain bent and accommodated in the accommodation space, where a first end of the drag chain is relatively fixed to the wire harness accommodation box, and a second end of the drag chain passes through the opening and is slidably disposed in a slideway of a lower slide rail of the seat; a wire harness threaded in the drag chain, where a first end of the wire harness passes through a first end of a wire harness channel and the opening to be connected to a power supply, and a second end of the drag chain passes through a second end of the wire harness channel to be connected to an upper slide rail of the seat.

A light emitting device includes a light emitter, a holding portion that slidably holds the light emitter inside a slide rail for a vehicle, and a light transmissive cover that covers the light emitter. According to a configuration, the cover of the light emitting device prevents a decrease in a communication performance of a signal transmission and reception device in which information on an electronic device is transmitted using an LED, as compared with a related art in which the communication performance decreases due to influence of scattering or shielding a light of the LED, the influence being caused by a grease which is heavily applied inside a slide rail of a vehicle and adheres to the LED.

Various vehicle seat improvements are enabled herein. For instance, a kinematic seat for a vehicle comprises a seat base connected to the vehicle. A first side member is affixed to a base at a first side of the base. A second side member is affixed to the base at a second side of the base, opposite the first side of the base. A slider is slidably received in the base. A seat back assembly is rotatably coupled to the first side member and rotatably coupled to the second side member. A linkage is rotatably coupled to the seat back assembly and rotatably coupled to the slider, whereby sliding of the slider rotates the seat back assembly. A first lower seat lifting mechanism comprises a lifting bracket, wherein the lifting bracket is rotatably coupled to the first side member at a first end of the lifting bracket, and wherein the lifting bracket is slidably received in a channel of the first side member at a second end of the lifting bracket. A second lower seat lifting mechanism comprises a bracket rotatably coupled to the base and a link arm rotatably coupled to the bracket and rotatably coupled to the slider.

A vehicle seat console has at least one vehicle-side guide element and at least one seat-side guide element that is arranged parallel to the vehicle-side guide element. At least one longitudinal adjustment device that is acted upon by a drive device is designed to bring about a relative adjustment between the vehicle-side guide element and the seat-side guide element. The longitudinal adjustment device is provided with a toothed rack and a gearwheel that is in meshing engagement with the toothed rack. The teeth of the gearwheel and/or the teeth of at least one section of the toothed rack are made of materials of different shear strength.

A system comprising a vehicle seat track, in particular automotive vehicle, and a support, where the track comprises a fixed profile intended to be added onto the chassis of the vehicle and a mobile profile configured for sliding relative to the fixed profile. The support comprises an engaging part forming a hook, where the engaging part is configured for engaging with the mobile profile in case of impact of the vehicle.

A vehicle seating assembly is provided that includes a platform. The platform includes a frame having an attachment feature. A seat base is coupled with the attachment feature. A cross-member is coupled to the frame and movable between extended and retracted positions. The seating assembly also includes a track assembly including a plurality of tracks received by guides. The platform extends between each of the plurality of tracks.

An assembly for a vehicle, which includes two adjustment rails, arranged spaced apart and extending in parallel, for a seat of the vehicle and at least one transverse strut extending transversely to the adjustment rails, which rigidly connects the two adjustment rails to one another, as well as a body shell structure for a vehicle and a floor for a vehicle.

An embodiment rail device includes an upper rail, a first bearing support on the upper rail, a lower rail, a bearing connection end on the lower rail and inserted into the first bearing support, a vertically elongated bearing contact adjustment hole on the lower rail, an upper bearing rotatably connected to the bearing connection end and in close contact with a floor of the first bearing support, a lower plate including a fastening groove that receives a lower end of the lower rail, a bearing shaft mounting hole on a wall surface portion of the fastening groove and matched with the bearing contact adjustment hole, a second bearing support outside the fastening groove and having an opened upper portion, a lower bearing rotatably disposed within the second bearing support, and a bearing shaft fastened to the bearing shaft mounting hole and the bearing contact adjustment hole by a screw.

A vehicle seat comprises: a seat base; a first side member is affixed to a base at a first side of the base; a second side member is affixed to the base at a second side of the base, opposite the first side of the base; a slider slidably received in the base; a seat back assembly is rotatably coupled to the first side member and rotatably coupled to the second side member; a linkage rotatably coupled to the seat back assembly and rotatably coupled to the slider; a first lower seat lifting mechanism comprising a lifting bracket, wherein the lifting bracket is rotatably coupled to the first side member at a first end of the lifting bracket; and a second lower seat lifting mechanism comprising a bracket rotatably coupled to the base and a link arm rotatably coupled to the bracket and rotatably coupled to the slider.

A long rail assembly for use in an automotive vehicle includes a fixed long rail, a rail drive assembly having a drive wheel for transposing the rail drive assembly along the fixed long rail, an upper gearbox attached to a vehicle seat, and an auto-centering quick connection mechanism for operatively coupling a guide pin extending from the upper gearbox to the drive wheel when the vehicle seat is attached to the rail drive assembly. The auto-centering quick connection mechanism further automatically rotates the guide pin to a home position when the vehicle seat is decoupled from the rail drive assembly.
