A seat rail for a vehicle includes a stopper part of a locking mounting bracket and a towel bar for inhibiting a misoperation of a release lever due to the feet of a rear seat passenger by inhibiting interference of the feet of the passenger with the release lever and inhibiting deformation of the towel bar when the towel bar is pressed down.

A seat sliding structure for a vehicle includes: a pair of left and right slide rails that include upper rails, which are attached to a lower portion of a vehicle seat, and lower rails, which support the upper rails such that the upper rails can slide in a vehicle longitudinal direction; rail guiding members that are fixed to a floor panel, and that support the lower rails such that the lower rails can slide in the vehicle longitudinal direction between a driving position at a vehicle front side and a relaxation position at a vehicle rear side; and a locking mechanism that locks movement of the slide rails at the relaxation position, and that releases a locked state when a frontal collision of the vehicle is detected or predicted.

Provided is a vehicle seat (100) comprising: a seat cushion (101); a seat back (102) capable of being folded toward the seat cushion (101); a slide rail (110) movable in the front-back direction with the seat cushion (101) mounted thereon; a stationary rail (120) for guiding the slide rail (110); and a drive motor (160) for driving the slide rail (110) in the front-back direction along the stationary rail (120). The vehicle seat (100) is configured such that an integral sensor bracket (130) on which a magnetism sensor (141) and a limit switch (151) are mounted is affixed to the slide rail (120), and a magnetic body (142) which is detected by the magnetism sensor (141) and a detection plate (153) which activates the limit switch (151) are mounted to the stationary rail (120).

A sliding device includes a fixed rail, a movable rail, a lock plate, a spring member, and a first stopper and a second stopper provided on the lock plate. The lock plate is held by the movable rail, and is displaceable between a locking position where the lock plate engages with the fixed rail and a non-locking position where the engagement is released. The spring member can exert an elastic force to maintain the lock plate in the locking position. The first stopper locks and fixes a first end of the lock plate to the spring member. The second stopper locks and fixes a second end of the lock plate to the spring member.

A sliding device includes a fixed rail, a movable rail, a lock plate, and a spring member. A seat body is fixed to the movable rail, and the movable rail is slidable relative to the fixed rail. The lock plate is held by the movable rail, and is displaceable between a locking position where the lock plate engages with the fixed rail and restricts slide of the movable rail and a non-locking position where the restriction is released. The spring member exerts an elastic force to maintain the lock plate in the locking position.

One example of a sliding device that can sufficiently reduce a separation phenomenon is disclosed. The sliding device includes a fixed rail, a movable rail, a fixed-side hook, an engagement hook, and a reinforcing hook. The fixed rail is configured to be fixed to a vehicle. To the movable rail, the seat body is attachable. The movable rail is slidable with respect to the fixed rail. The fixed-side hook is configured to be fixed to the vehicle. The engagement hook is provided to the movable rail. The engagement hook is engageable with the fixed-side hook, and is formed by a first plate material curved approximately into a letter J or U shape. The reinforcing hook overlaps with the engagement hook in a thickness direction of the first plate material. The reinforcing hook is formed by a second plate material curved approximately into a letter J or U shape.

The present disclosure relates to a seat rail for a vehicle having a lever shaft configured to be integrally combined with bracket flanges, whereby shaking of a release lever in the forward/backward and leftward/rightward directions may be reduced. When the release lever is rotated in a restoring direction thereof by an elastic force of a lever spring, lever flanges make contact with a locking mounting bracket and a restoring rotation of the release lever stops. In addition, an end portion of the lever spring may be held by and fixed to the release lever so as to improve operability of a locking pin.

A seat sliding device for vehicles includes lower and upper rails and a locking member for locking or unlocking the upper rail relative to the lower rail. The upper rail is equipped at a lower end of its downward side wall portion with a lower inward corner portion formed of a raised wall portion and a bottom wall portion. The locking member has an axial portion that is placed on and biased against the lower inward corner portion of the upper rail such that the locking member is swingable about an axis of the axial portion to lock or unlock the upper rail relative to the lower rail. This seat sliding device makes it possible to reduce the number of parts and improve operation stability of the locking member.

In the present invention, in a bottom portion 4a of a lower rail 4, a foreign matter interference portion 27 protruding upward and having a substantially arc-circular shape in a side view is formed by being cut and raised in a middle part in a rail width direction more on a front side than a bolt hole 26 for a mounting bolt for fixing the rear end portion of the lower rail 4 to a vehicle body. Rear-side stoppers 29 and long hole portions 31 shared with the rear-side stoppers 29 are formed on both sides of the foreign matter interference portion 27. The foreign matter interference portion 27 is separated into a front-side tongue piece 27a and a rear-side tongue piece 27b by a slit 32.

A sliding device of the present disclosure includes: a fixed rail; a movable rail; a rack fixed within the fixed rail, the rack extending along an axis parallel to a longitudinal axis of the fixed rail; a pinion provided to the movable rail, the pinion including multiple teeth to be engaged with the rack and rotating by receiving a driving force; and a restrictor slidingly displaced integrally with the movable rail, the restrictor contacting with the rack when the movable rail is sliding, to thereby restrict the rack from being displaced in a direction away from the pinion.
