Provided is a slide device that can prevent rattling of a seat with a simple structure. A slide device includes a lock mechanism for fixing an upper rail to a lower rail. The lock mechanism includes a shaft attached to the upper rail, a lock tooth swingably supported by the shaft, and a wave washer that presses the lock tooth in an axial direction of the shaft. An outer circumferential face of the shaft has an outer tapered face slanted so that the shaft becomes thinner along a direction from a proximal end portion toward a distal end portion. An inner circumferential face of the shaft hole of the lock tooth has an inner tapered face having a slant angle that allows face-to-face contact with the outer tapered face. The wave washer presses the lock tooth in a direction in which the inner tapered face is pressed against the outer tapered face to make face-to-face contact.

A sliding unit for a vehicle includes: a rail including a first extension part, a second extension part, and a bending part connecting the first extension part and the second extension part; a movable part slidably disposed on the rail, and including a magnetic part configured to be locked with or unlocked from the rail; a power supply part disposed in the rail, having a shape extending in a lengthwise direction along the rail, and electrically connected to a power source of the vehicle; and a first contact part and a second contact part disposed in the movable part, and electrically connecting the power supply part and the magnetic part when contacting the power supply part.

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.

An anchor for a support member of a track system may include an anchor body and a toothed anchor portion. The anchor body may be connectable to said support member. The toothed anchor portion may include a plurality of anchor teeth configured to engage a plurality of track teeth of a toothed portion of a track assembly. The anchor body and the toothed anchor portion may be connected to one another to collectively form a hook portion configured to engage said toothed portion of said track assembly. At least a subset of anchor teeth of the plurality of anchor teeth may be disposed one after another in a curved or angled configuration to define a curved or angled row of anchor teeth.

The present invention provides a seat-sliding apparatus for a vehicle. The seat-sliding apparatus includes a lower rail fixed to the vehicle, an upper rail, which is coupled to a seat and slides along the lower rail, a rail groove portion, which is formed in at least one surface of the lower rail and has therein a plurality of grooves, a tooth portion having teeth positioned between the grooves in the rail groove portion, a sloped portion, which is positioned at at least a portion of the rail groove portion and in which heights of the teeth of the tooth portion decrease toward a center of the rail groove portion from one end of the rail groove portion in a longitudinal direction, and a locking unit, which is positioned at the upper rail and is selectively engaged with the rail groove portion so as to hold the upper rail.

The invention relates to a vehicle seat having a roller guide which has at least one guide rail which is at least partially sideways open and at least one running roller rolling in the guide rail, connected to parts of the vehicle seat via an axle member, wherein a running surface of the running roller is rollable along a roller-underside inner wall of the guide rail arranged parallel or at an angle to a middle axle of the running roller, wherein the running roller comprises at least a first area and a second area, wherein the first area forms at least a part of the running surface and the second area is arranged in a radial direction of the running roller at least partially between the axle member and the first area and in contact with both. According to the invention, an electrical conductivity of the first area is lower than an electrical conductivity of the second area.

Provided is a slide device that can prevent rattling of a seat with a simple structure. A slide device includes a lock mechanism for fixing an upper rail to a lower rail. The lock mechanism includes a shaft attached to the upper rail, a lock tooth swingably supported by the shaft, and a wave washer that presses the lock tooth in an axial direction of the shaft. An outer circumferential face of the shaft has an outer tapered face slanted so that the shaft becomes thinner along a direction from a proximal end portion toward a distal end portion. An inner circumferential face of the shaft hole of the lock tooth has an inner tapered face having a slant angle that allows face-to-face contact with the outer tapered face. The wave washer presses the lock tooth in a direction in which the inner tapered face is pressed against the outer tapered face to make face-to-face contact.

A vehicle seat includes a pair of side frames disposed separately from each other in a lateral direction; a pair of connecting frames disposed separately from each other to connect the pair of side frames; and a supporting member including hook portions hooked on the pair of connecting frames, the supporting member being laid to bridge the pair of connecting frames, and configured to support an occupant, wherein a tubular member in which a connecting frame is disposed is provided in a position between the hook portions and the side frames. The tubular member is configured to contact the hook portion to thereby restrict a position of the supporting member in the lateral direction.

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.
