Claims (1)

[Scope of utility model registration request] A secondary seat rest is placed approximately horizontally at an appropriate distance to the side of a supporting wall such as a main seat rest or an armrest, and an external pivot point is provided on the secondary seat, and the external pivot point is placed on the supporting wall at a higher position than the external pivot point. A pivot point is provided, the outer pivot point and the upper pivot point are connected by the upper rod, an inner pivot point is provided closer to the support wall than the outer pivot point in the sub-rest, and an inner pivot point is provided on the support wall. A lower pivot point is provided at a lower position than the point,
The lower pivot point and the inner pivot point are connected by a lower rod, and the upper surface of the extension of the lower rod beyond the inner pivot point contacts the lower surface of the upper rod or the lower surface of the sub-rest; The upper pivot point and the lower pivot point are arranged so that when the end of the sub-rest farthest from the supporting wall is rotated upward around the inner pivot point and the outer pivot point, the sub-rest can be positioned almost vertically. pivot point, internal pivot point,
An auxiliary seat that can be stored in an armrest that determines the position of the external pivot point and the dimensions of the upper and lower rods.
