A sliding rail transmission device and a vehicle include a driving portion and at least one sliding rail assembly, the sliding rail assembly includes a rail and a movable member, the rail is provided with a flanging which extends downward, the flanging forms a first transmission toothed belt, and the rail is provided with a damping strip at a position of the first transmission toothed belt, the damping strip forms a second transmission toothed belt, the first transmission toothed belt and the second transmission toothed belt are arranged side by side, the movable member is provided with a transmission gear, the transmission gear is arranged below the first transmission toothed belt and the second transmission toothed belt, and the transmission gear can mesh with the first transmission toothed belt and the second transmission toothed belt simultaneously; and the driving portion drives the transmission gear to rotate to drive the movable member to move along the rail. Such arrangement is beneficial to realizing stable driving, and foreign matters are not easy to fall into the first transmission toothed belt and the second transmission toothed belt. The first transmission toothed belt and the second transmission toothed belt are arranged side by side and mesh with the transmission gear together, which not only ensures the overall strength of the transmission toothed belts, but also achieves the object of vibration damping and is beneficial to enhancing the adaption of tolerance.

A roller mount for seats is used in connection with a boat and a seat. First and second base slides are mounted spaced apart on a base plate. The base slides have longitudinal rack gears. First and second top slides are mounted for linear movement on the base slides in a longitudinal direction, on a plurality of rollers. A top plate is mounted on the top slides to support the seat. First and second detent plates have longitudinal top rack gears, for selective releasable engagement with the base rack gears to preclude movement of the top slides. First and second locking bars extend longitudinally adjacent the base rack gears. The top rack gears include locking slots extending longitudinally for engagement with the locking bars, to guide the top rack gears into engagement with the base rack gears. The base rack gears and the top rack gears have teeth extending upward and inward at an angle with the base plane. The downward vector force created by the angle will eliminate backlash between the locking bar and the locking slot.

A sliding device for a vehicle seat is provided. The sliding device includes a pair of parallel slideways, each of which comprises a lower rail, an upper rail slidably mounted to the lower rail and a latch for allowing/preventing a movement of the upper rail relative to the lower rail. A releasing member is provided for driving the latches to a position in which the upper rails are free to move relative to the lower rails. Each latch has a rear portion which is bent into a “U”-like shape and comprises a lower leg carrying latching elements configured to cooperate with corresponding latching elements provided in the lower rail and an upper leg configured to engage the releasing member. The design of the latches improves the reliability of the sliding device.

A track assembly includes a track and a support member connected to and configured move along the track. The support member may include an engagement portion. The engagement portion may be configured to engage the track to limit relative movement between the track and the support member in a loaded state of the track assembly. The engagement portion may be configured not to operatively engage the track or limit movement between the track and the support member in an unloaded state of the track assembly.

In an electric seat slide device of the present invention, a rear-side bracket 27 includes a first support member 41 fixed to a lower rail 2, a second support member 42 fixed to the lower rail 2 together with the first support member 41, a female screw member 43 as a first nut member through which a screw shaft 4 passes, and a second nut member 44 through which the screw shaft 4 passes. A pair of side wall portions 47 extending along a lower rail longitudinal direction and a vertical wall portion 62 of the second support member 42 which is formed orthogonal to the straight line along the lower rail longitudinal direction are sandwiched between the female screw member 43 and the second nut member 44.

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.

A track assembly for a rail-mounted component of a vehicle includes a rail cartridge slidably coupled with a track and defines a first slot. A first electrical connector is positioned within the rail cartridge. A connection cartridge defines a channel. The connection cartridge includes first and second sidewalls joined by a bottom wall. A second electrical connector is positioned within the channel and is configured to selectively engage with the first electrical connector. An actuation member is positioned within the channel and is movable between first and second positions. The actuation member is biased to the first position. An actuator is operably coupled with the actuation member to selectively move the actuation member into the second position against the bias.

Provided is a vehicle seat including: a seat cushion supported by a support member so as to be rotatable around an axial direction along the seat up-down direction; a seatback configured such that the angle of the seatback relative to the seat cushion is adjustable by unlocking and locking of an angle adjustment mechanism, the seatback being biased to be tilted forward in the seat front-rear direction when the angle adjustment mechanism is unlocked; an operated member configured to unlock and lock the angle adjustment mechanism, the operated member being placed on a first end side of the seat cushion in the seat width direction; and an operating member provided in the support member such that the operating member is configured to relatively operate the operated member along with a rotation of the seat cushion so as to unlock the angle adjustment member.

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.

A track assembly includes a first track having first apertures, a second track having second apertures, and a latch assembly. The latch assembly includes a latch plate movable between an engaged position and a disengaged position. The latch plate includes first teeth that selectively extend through the first apertures and through at least one of the second apertures when the latch plate is in the engaged position. A gap is present between a first latch tooth of the first teeth and one of the first apertures when the latch plate is in the engaged position. The latch assembly includes an anti-chuck component coupled to the latch plate and including a second tooth that extends along a face of the first latch tooth. The second tooth extends laterally past both lateral edges of the first latch tooth to close the gap when the latch plate is in the engaged position.
