Problems solved by technology

As a result, the lower rail 2 continuously and strongly collides with the bearings 5, 6, and 7 when the upper rail 3 is slid or when the moving vehicle vibrates, which causes damage to the bearings 5, 6, and 7 or damages the seat rail 1. Reduced durability
[0009] In addition, there is also the problem of noise due to the collision between the lower rail 2 and the bearings 5, 6 and 7

Embodiment Construction

[0023] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] image 3 and 4 are an assembled perspective view and an exploded perspective view of a seat rail according to an embodiment of the present invention.

[0025] The seat rail 9 according to the embodiment of the present invention includes a lower rail 10 , an upper rail 20 and a locking mechanism 30 . The lower rail 10 includes a rail groove 10a therein and is fixed to a floor in the vehicle in the longitudinal direction of the vehicle. The upper rail 20 has an upper portion fixed on the cushion frame and a lower end portion fitted to the rail groove 10a to reciprocate along the rail groove 10a. The locking mechanism 30 is fixed on the upper rail 20 and selectively locked on the lower rail 10 to limit the movement of the upper rail 20 .

[0026] In addition, as shown in the figure, the seat rail 9 according to the embodiment of the prese...

Abstract

The invention relates to a vehicle chair lead rail. The vehicle chair lead rail is directly fixed on a floor without individual accessories, thereby being capable of improving the design freedom of fixing a plurality of chair lead rails on a small floor and obtaining a satisfying beautiful appearance; besides, the manufacturing cost can be reduced by reducing the quantities of parts. Besides, the left bearing and the right bearing of a rolling unit fixed on an upper lead rail can be alternatively contacted with the upper bottom part and the upper wall of a lead rail slot. Therefore, the rolling unit does not move up and down relative to the upper lead rail in the lead rail slot (namely no clearance relative to the upper lead rail is arranged in the lead rail slot). As a result, the durability of the whole chair lead rail can be improved and the noise in the vehicle can be reduced.

Description

technical field [0001] The present invention relates to a seat rail that allows a vehicle seat to slide. Background technique [0002] Generally, a vehicle seat is provided in a vehicle to slide toward the front side or the rear side of the vehicle. In this case, the seat rail 1 shown in FIG. 1 is used to allow the vehicle seat to slide toward the front side or the rear side of the vehicle. [0003] Short rails are used to allow the driver's and passenger seats to move in a normal car that includes two rows of seats. Conversely, short rails are used in the first row of seats and long rails are used in the other rows of seats to allow the seats to be used in vehicles such as vans with two or more rows of seats as shown in FIG. move in. [0004] In this case, as shown in FIG. 2 , each seat rail 1 of the vehicle includes a lower rail 2 , an upper rail 3 , a locking mechanism 4 and a plurality of bearings / supports 5 , 6 and 7 . The lower rail 2 is fixed to the floor in the v...
