Claims

[Claims for Utility Model Registration] (1) An armrest is provided so as to be able to stand up and fall down via a removable support shaft at the outer end of the seat back, and a means for preventing the support shaft of the armrest from coming off the seat back can be released. A seat with an armrest, characterized in that it is provided with an armrest. (2) As a means for preventing the armrest from falling off, a torsion bar is used that is removably and elastically locked in a groove formed in the support shaft of the armrest, and that the locked state is maintained by being pressed against the shaft that limits the rotation of the armrest for standing up and falling down. Claim 1 characterized in that it is provided on the seat back side.
Seat with armrest as described. (3) The seat with an armrest according to claim 1, wherein a torsion bar with an operation knob is provided on the seat back side as a means for preventing the armrest from coming off, and the torsion bar has an operation knob that is elastically engaged in a groove formed in the support shaft of the armrest in a detachable manner. (4) The armrest according to claim 1, wherein when one of the left and right seat bags is folded forward or backward, the armrest at the outer end of the one seat bag can be removed and attached to the inner end of the other seat bag. Comes with a sheet.
