Problems solved by technology

[0005] However, in the seat rail sliding device of the above-mentioned publication, in order to prevent the upper rail 110 from detaching from the lower rail 100, it is necessary to provide a holding member 130 as a dedicated part, so the number of parts increases, and the cost and weight also increase.

Embodiment Construction

[0022] First refer to Figure 1 to Figure 8 The locking mechanism of the seat rail slide device according to the first embodiment of the present invention will be described.

[0023] Such as figure 1 As shown, the seat rail sliding device 1 of this embodiment has: a pair of lower rails 3 (only one shown) extending in the front-rear direction X of the vehicle; A pair of upper rails 5 (only one is shown) extending in the direction X. The two lower guide rails 3 are arranged parallel to each other at predetermined intervals in a direction perpendicular to the front-rear direction X of the vehicle, that is, in the width direction of the vehicle, and are fixed to the floor 2 of the vehicle body. The two upper rails 5 are respectively fixed to both side portions of the seat 4 in the width direction of the vehicle. Each upper rail 5 is movable in the front-rear direction X relative to the corresponding lower rail 3 .

Abstract

In the locking mechanism of the present invention, a pair of upper guide parts (14) respectively extending from the two side wall parts (13) of the upper guide rail (5) and a pair of respectively extending from the two side wall parts (7) of the lower guide rail (3) Engage with the lower guide part (8). A locking lever (18) and a torsion coil spring (25) are provided between the two side walls (13) of the upper guide rail (5), which can selectively allow or prevent the movement of the upper guide rail (5) relative to the lower guide rail (3). move. The helical part (26) of the torsion coil spring (25) has a space keeping function capable of keeping the space between the two side wall parts (13) of the upper rail (5). The torsion coil spring (25), which is a part of the locking mechanism, is used as a component for preventing the upper rail (5) from detaching from the lower rail (3), thereby reducing the number of parts.

Description

technical field [0001] The present invention relates to a locking mechanism in a seat track slide for a vehicle, and more particularly to a lock that is selectively switchable between a locked state that prevents movement of the upper rail relative to the lower rail and an unlocked state that permits movement of the upper rail mechanism. Background technique [0002] A general seat rail slide device includes a pair of lower rails fixed to the floor of a vehicle body, and a pair of upper rails supported so as to be movable relative to the lower rails. The two upper guide rails are fixed on the vehicle seat. Figure 13 A cross-sectional view showing the seat rail sliding device disclosed in Japanese Patent Laid-Open No. 10-287155, particularly one of the lower rails 100 and one of the upper rails 110 supported by the lower rails 100 . The lower guide rail 100 has a pair of side wall portions 101 , and a pair of lower guide portions 102 are respectively bent and extended from ...
