Description

  The present invention relates to a slide mechanism that slidably supports a sheet, for example.

  2. Description of the Related Art Conventionally, a rotary slide seat device that supports getting on and off of a vehicle is known (see, for example, Patent Literature 1 and Patent Literature 2). It has a slide mechanism.

  As shown in FIG. 8, the slide mechanism includes a rail 801 that is fixed to the vehicle body and a slider 802 that is a swivel lower that is movably supported by the rail 801.

  Rail support portions 811 supported by the rail 801 are provided on both sides of the slider 802 (only one of them is shown in FIG. 8). The rail support portion 811 is connected to the lower component member 812 of the rail 801. It is slidably held in a state of being sandwiched between the upper structural member 813. The upper component member 813 and the lower component member 812 are formed with flanges 814 and 815 extending laterally, and the upper component member 813 and the lower component member 812 are connected by the flanges 814 and 815. And can be fixed. Supporting portion side holding grooves 816,... Are formed on the lower surface and the upper surface of the rail supporting portion 811. The upper component member 813 and the lower structure facing the supporting portion side holding grooves 816,. Opposite grooves 817,... Are formed in the part of the member 812.

Japanese Patent Laid-Open No. 2004-074865 Japanese Patent Laid-Open No. 9-039622

  However, in such a slide mechanism, the lower component member 812 and the upper component member 813 of the rail 801 are configured as separate members for the convenience of adjusting the rail width in accordance with the width dimension of the slider 802. Both constituent members 812 and 813 are provided with flanges 814 and 815 for connecting and fixing the constituent members 812 and 813 together.

  For this reason, from the rail 801, flanges 814 and 815 provided on the two component members 812 and 813 extend laterally as ear portions 831. Thereby, there existed a problem that the width dimension which the said rail 801 occupies became large.

  The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a slide mechanism capable of reducing the width dimension occupied by the rail.

  In order to solve the above problems, the sliding mechanism according to claim 1 of the present invention comprises a slider that supports the seat and a rail that is provided on the vehicle body side that slidably supports the slider. In a slide mechanism that slidably holds a support portion that extends laterally provided on both side portions in a state of being sandwiched from above and below by a holding portion provided on the rail, the base is disposed at a fixed location. And the holding portions provided on both side portions of the base portion, and both holding portions are formed in a folded shape opened toward the inside of the rail, while one support portion of the slider is provided. The first member and the second member provided with the other support portion are configured as separate members, and the fixing position of the second member with respect to the first member is determined by the slider. Adjustably fixed direction.

  In other words, when the slider is attached to the rail installed on the vehicle body side, the support portions provided on both sides of the slider are inserted into the holding portions provided on the rail and can be slid in a state of being sandwiched from above and below. Hold on. At this time, folded-back holding portions that open toward the inside of the rail are formed on both side portions of the base portion of the rail, and the support portions on both sides of the slider are inserted into the holding portions. Must be formed.

  Here, the first member provided with one support portion of the slider and the second member provided with the other support portion are configured as separate members, and the second member with respect to the first member The fixing position is fixed so as to be adjustable in the width direction of the slider.

  For this reason, when a molding error or the like occurs, the width dimension of the slider with respect to the rail is adjusted by adjusting the fixing position of the second member with respect to the first member.

  Further, in the slide mechanism of claim 2, in particular, both holding portions are integrally formed in the slide mechanism of claim 1.

  Thereby, simplification of a structure can be achieved.

  As described above, in the sliding mechanism according to the first aspect of the present invention, even if a molding error occurs in the width dimension between the slider and the rail, the second member with respect to the first member constituting the slider. This molding error can be absorbed by adjusting the fixed position of the.

  For this reason, for the convenience of adjusting the width dimension according to the slider, the rail is composed of a separate lower constituent member and upper constituent member, and both constituent members are connected and fixed to both constituent members. Compared with the prior art in which it is necessary to provide a flange, it is possible to eliminate the ear portion composed of a flange extending laterally from the rail. Thereby, the width dimension of a rail can be made small and the exclusive area which a rail occupies can be suppressed.

  Further, in the slide mechanism according to the second aspect, in particular, both holding portions are integrally formed.

  For this reason, simplification of a structure can be achieved.
