TECHNICAL FIELD OF THE INVENTION
The present invention relates to a seatbelt structure for a vehicle, and more particularly to a seatbelt structure provided near a seat which is provided so as to be able to move up and down.
[0002]
[Prior art]
In general, it is preferable that the seat belt provided on the pillar portion on the outer side of the vehicle be disposed so as not to interfere with the seat in a non-fastened state. There is disclosed one that is held at a position separated from the back toward the vehicle front or the outside of the vehicle to prevent interference with the seat back.
Japanese Utility Model Publication No. 3-44603 discloses a sewing machine in which a sewing stitch is provided on a seat belt portion above an anchor portion to impart autonomy to the portion.
[0003]
[Problems to be solved by the invention]
By the way, in order to increase the luggage space, the seat is provided so as to be movable up and down toward the vehicle front side or the vehicle rear side, and is arranged along the pillar portion when the seat is flipped up and stored. There is a possibility that the seatbelt is displaced in the direction of the stored seat by being sandwiched between the seat back of the seat and the seat cushion.
[0004]
In the seat as described above, a locking member that engages with an engaging member provided on the seat cushion side and fixes the seat cushion to the vehicle body so that the seat cushion can be seated is provided on the vehicle body floor or the like. As described above, if the seat belt is kept displaced in the seat direction in which the seat belt is stored when the seat is stored, the seat is returned between the engagement member and the locking member when the seat is returned to the seatable state. There is a problem that the seat belt is easily pinched, and the engagement between the two cannot be reliably performed.
[0005]
However, in the conventional example, the seat belt is not intended to prevent the seat belt from being pinched between the engaging member and the locking member of the sheet provided to be capable of being flipped up and stored as described above. It cannot solve the above technical problem.
[0006]
The present invention has been proposed in order to solve the problems of the prior art, and an object of the present invention is to provide a seat having a flip-up retractable seat as described above, in which the seat belt is particularly in such a state as described above. In this case, the seat of the vehicle can be prevented from being caught between the engaging member and the locking member with a simple structure, so that the two can be securely engaged with each other. It is to provide a belt structure.
[0007]
