The sliding rail assembly solves the problem of shaking during seat adjustment, and has enough bearing capability.

An assembly of a vehicle comprises a floor assembly stationarily arranged in the vehicle and an adjusting device for longitudinally adjusting a vehicle seat in a vehicle comprising a guide rail connected to the floor assembly and extending along a longitudinal axis on the floor assembly, and an adjustment assembly associated with the vehicle seat, which is guided on the guide rail along the longitudinal axis. It is provided that the guide rail includes at least one connecting element which includes an engagement portion for the form-fitting engagement into an engagement device arranged on the floor assembly on a first side of the guide rail and a connecting portion with a fixing point for fixing the connecting element to the floor assembly by using a fixing element on a second side of the guide rail facing away from the first side.

A rail assembly includes a track assembly with a retaining lip and a carriage assembly that is received within the track assembly. The carriage assembly includes a body portion, an exterior surface of the body portion, and a retaining bracket fastened to the exterior surface. The retaining bracket extends outwardly from the point at which the retaining bracket is fastened to the exterior surface. The retaining bracket defines a notch that receives the retaining lip of the track assembly.

Methods for enhancing the sliding performance of an adjusting device for longitudinal adjustment of a vehicle seat are disclosed. The adjusting device comprises a first rail and a second rail movably guided relative to the first rail. Friction-reducing members are disposed between the two rails in a bearing area. The geometry and dimensions of the friction-reducing members are precisely adjusted in accordance with the geometry and dimensions of the two rails in the bearing areas, which are measured separately. The friction-reducing members may be produced using additive manufacturing technology, with a geometry and dimensions precisely in accordance with the geometry and dimensions of the two rails. The friction-reducing members may also be produced using conventional injection molding, whereas the geometry and dimensions of the friction-reducing members are adjusted subsequently by varying the thickness of friction-reducing layers or coatings applied to outer surfaces of the friction-reducing members using e.g. ablative techniques.

A vehicle seating assembly includes a seat back. A seat base is coupled to the seat back. A track assembly and the seat base are translatable fore and aft along the track assembly. A rail cartridge slidably engages with the track assembly. An actuation assembly includes a first electrical connector coupled to the rail cartridge and a support member coupled to a second electrical connector. The second electrical connector is operable between engaged and disengaged positions relative to the first electrical connector via a sliding engagement of the support member along opposing grooves of an engagement member. The second electrical connector is actuated via an actuator coupled to the second electrical connector.

A power slide includes a left slide and a right slide, each including a top rail, a bottom rail, a lead screw and an electric motor. The top rail is arranged above the bottom rail and is slidably connected to the bottom rail, and a notch is formed in a middle portion of the top rail. The lead screw is arranged above the bottom rail in parallel and has two ends fixedly connected to the bottom rail. The electric motor includes a housing, a rotor shaft and a stator shaft. The housing is mounted in the notch, the stator shaft is fixedly connected into the housing, the rotor shaft penetrates into the stator shaft and is rotatably connected to the stator shaft, and an interior of the rotor shaft is threadedly connected to the lead screw.

A track assembly includes a track and/or a support member. The track may include a first ramped portion and/or a second ramped portion. The support member may include a rolling member. A first side of the rolling member may include a first contact portion, and/or a second side of the rolling member may include a second contact portion. The support member may be configured to move along the track via rotation of the rolling member. The first contact portion and/or the second contact portion may be configured to contact the first ramped portion and/or the second ramped portion. The rolling member may include a flange that may be configured to engage an inner portion of the track. The inner portion may be substantially vertical. The track may include an opening that may be disposed between the inner portion and/or a second inner portion of the track.

A track assembly includes a track and a support member. The support member may include a slider and/or an electrical connector. The slider may be configured to move longitudinally to move the electrical connector between a first rotational position and/or a second rotational position. In the first position of the electrical connector, the electrical connector may be in electrical contact with the track. In the second position of the electrical connector, the electrical connector may not be in electrical contact with the track. The electrical connector may include a cam, and/or the cam may be configured to contact the slider. Longitudinal movement of the slider may rotate the cam to move the electrical connector between the first rotational position and/or the second rotational position. The slider may include a first ramped portion and/or a second ramped portion that may be configured to contact the slider.

A vehicle seat structure includes a vehicle seat including a seat cushion configured to support an occupant, an upper rail that is fixed to the vehicle seat and that moves in a seat front-rear direction together with the vehicle seat, and a lower rail that is fixed to a floor of a vehicle body and that engages with the upper rail and supports the upper rail so as to allow movement of the upper rail. The vehicle seat structure includes a lock mechanism configured to restrict movement of the upper rail with respect to the lower rail. The lock mechanism is configured such that at least part of the lock mechanism deforms when a force toward the seat front side arising due to inertia acts on the vehicle seat in a state in which the upper rail is engaged with a seat rear side portion of the lower rail.
