Embodiment Construction

[0032] Such as Figure 4 As shown, seat rails 100 for a vehicle according to an exemplary embodiment of the present invention are provided in pairs on left and right sides. Each upper rail 110 is connected to the lower surface of the vehicle seat, and each lower rail 120 is fixedly installed on the vehicle chassis.

[0033] The upper guide rail 110 is configured to be able to slide back and forth relative to the lower guide rail 120 . The locking and unlocking operations of the upper rail 110 and the lower rail 120 are performed using the locking frame 160 through the operation of the operating lever 170 and the linkage of the unlocking lever 180 . The locking operation and unlocking operation of the locking bracket 160 will be described later.

[0034] To specifically describe the structure of the seat rail 100 for a vehicle, as Figure 5 As shown, the upper rail 110 on the upper side and the lower rail 120 on the lower side are connected together so as to be able to slide...

Abstract

The invention relates to a seat track for a vehicle. The seat track for a vehicle comprises an upper track, a lower track, supporting balls, a holder and a roller. The upper track has a horizontal extending part, an outer wall part and an inward horizontal part. The lower track has a bottom part which is opposite to the horizontal extending part, an inner wall part which is arranged in an inner part of the outer wall part, and an outward horizontal part which is arranged to be opposite to the inward horizontal part. The supporting balls are in contact with the outer wall part and the inner wall part in a transverse direction, and are in contact with the inward horizontal part and the outward horizontal part in a vertical direction. The holder uses each transverse end parts thereof to hold and support the supporting balls. An upper end of the roller supports the horizontal extending part, and a bottom part supports a lower end of the roller, thus the roller supports the sliding of the upper track relative to the lower track and enables the upper track to slide smoothly. Therefore, the seat track can be provided which has good operating performance and a stable structure, and the noise generated by low sliding friction of the upper track is relatively small.

Description

technical field [0001] The present invention relates to a vehicle seat rail for front and rear sliding adjustment of a vehicle seat. Background technique [0002] Usually, such as figure 1 As shown, a seat rail 1 used in a commercial vehicle such as a truck includes an upper rail 10 and a lower rail 20 connected to each other up and down, and balls 30 and rollers 40 for sliding between the rails 10 and 20 . [0003] The balls 30 are respectively in contact with the horizontal portion 11 and the vertical portion 12 of the upper guide rail 10 and the corner portion 21 of the lower guide rail 20 to roll. The balls 30 are supported by the cage so that there is a predetermined relationship between the left ball 30 and the right ball 30 . [0004] The rollers 40 contact the horizontal portion 11 of the upper rail 10 and the bottom 22 of the lower rail 20 in the vertical direction to support the upper rail 10 and roll. [0005] However, according to this conventional seat rail 1...
