Description

  The present invention relates to a seat device mounted on a vehicle, and more particularly to a seat device in which a long slide rail is positioned on a vehicle body floor with a high degree of parallelism and a method for manufacturing the same.

  In recent years, in RV (recreational vehicle) vehicles and the like, a rear seat is provided on a pair of long slide rails and can be slid in the front-rear direction of the vehicle body. As a result, the vehicle interior space can be effectively utilized in accordance with the number of passengers and the amount of loaded luggage.

  The long slide rail is fixed so as to straddle the two panels joined to the front and rear. Conventionally, long slide rails have been positioned on the vehicle body floor using fixing holes that are bolted to the vehicle body floor. Specifically, the rail is fixed by using the rail fixing hole positioned at the foremost side of the rail as a reference hole and the rail fixing hole positioned at the rearmost side of the rail as a vertically long hole.

  However, in this method, since the rail is fixed across two panels, if the welding position of the rail mounting nut of each panel is shifted in the vehicle body width direction, the mounting position of each rail varies and becomes parallel. The degree gets worse. In addition, even if the welding positions of the nuts in each panel coincide with each other in the vehicle body width direction, if the panels are joined in a state shifted in the vehicle body width direction, the positions of the rails fixed to the vehicle body floor will vary and the parallelism will be different. Deteriorate. Furthermore, the dimensional accuracy of the body frame also affects the parallelism of each rail. Thus, if the accuracy of the parallelism of each rail is poor, the sliding load of the rear seat cannot be reduced.

Therefore, various positioning methods have been proposed in order to fix the rail to the vehicle body floor with good parallelism.
For example, (1) there is a method in which an inner rail and an outer rail are set on a jig, mounted on a vehicle with parallelism and fixed to a vehicle body floor with bolts. Further, (2) there is a method in which the inner rail and the outer rail are attached to the seat before mounting on the vehicle, and the distance between the inner rail and the outer rail is regulated by the seat. Specifically, for example, when the seat is located behind the rail, after fixing the rear side of the rail to the vehicle body floor, sliding the seat forward, fixing the front side of the rail to the vehicle body floor, Regulate the interval. (3) The inner rail and the outer rail are attached to the seat before mounting on the vehicle, the spacing is regulated by the seat located behind the rail, and the positioning pin is set on the front side of the rail without the seat, There is a method of regulating the above (see Patent Document 1).

On the other hand, when mounting the seat after mounting the rail on the vehicle, (4) a reference hole on the front side of the inner rail, a vertically long hole on the back side, a horizontally long hole on the front side of the outer rail, and a large hole vertically and horizontally on the back side. There is a method of providing and positioning the seat in the longitudinal and lateral directions on the inner rail side.
JP 2002-331860 (paragraphs 0009 to 0012, FIG. 1)

  However, the method (1) has a problem that the number of steps for setting the rail on the jig increases. Further, the method (2) has a problem that the number of man-hours for sliding the sheet back and forth in the line work increases. Further, in all the methods (1) to (3), since the seat and the two rails are simultaneously mounted on the vehicle, there is a problem that workability is deteriorated due to an increase in weight.

  In the method (4), when the seat is mounted after the rail is mounted on the vehicle, the front side of the inner rail is a reference hole and the rear side is a vertically long hole, so that the rear side is tightened after the front side is tightened. Then, the bolt was tightened in the state where the hole and the nut were not located, and the bolt was raised. Or workability is not good, such as temporarily tightening the front side and finally tightening the rear side and then tightening the front side again.
