Abstract

An armrest according to the technology described herein includes a bracket, an armrest body, a device connecting port, an armrest-side connector, and a cable. The bracket is fixed to a seat frame. The armrest body is attached to the bracket to be rotatable. The device connecting port is exposed through an outer surface of the armrest body. The armrest-side connector is fixed to the seat frame at a position different from the bracket. The cable includes an end connected to the device connecting port and an end connected to an armrest-side connector. The armrest body includes a cable retaining portion through which the cable is passed and in which the cable is retained. Any one of the bracket and the armrest body includes a hole (an elongated hole) that allows movement of the cable along with rotation of the armrest body.

First claim

What is claimed is:

1. An armrest comprising:
a bracket fixed to a seat frame;
an armrest body attached to the bracket to be rotatable;
at least one device connecting port exposed through an outer surface of the armrest body;
an armrest-side connector fixed to the seat frame at a position different from the bracket; and
a cable including an end connected to the at least one device connecting port and an end connected to the armrest-side connector, wherein
the armrest body includes a cable retaining portion through which the cable is passed and in which the cable is retained,
any one of the bracket and the armrest incudes a bolt hole through which a shank of a bolt for attaching the armrest body to the bracket is passed, an elongated hole in which the cable moves along with rotation of the armrest body, and a guide pin that moves in a guide hole provided in another one of the bracket and the armrest body for guiding the rotation of the armrest body, and
the elongated hole is provided between the bolt hole and the guide pin.

2. The armrest according to claim 1 , further comprising a cable holder for holding the cable with the armrest body at an end of the cable retaining portion on an opposite side from the at least one device connecting port, wherein
the elongated hole is provided in the bracket,
the elongated hole is in an arc form with a rotation axis of the armrest body as a center of curvature, and
the cable pulled out of the cable holder toward the bracket moves in the elongated hole along with the rotation of the armrest body.

3. The armrest according to claim 1 , wherein
the armrest body is rotatable between a horizontal position and a vertical position, and
the at least one device connecting port includes a front device connecting port disposed at a front end of the armrest body in the horizontal position and a rear device connecting port disposed at a rear end of the armrest body in the horizontal position.

4. The armrest according to claim 3 , wherein the rear device connecting port is disposed more to a rear side than a rotation axis about which the armrest body rotates, and
the rear device connecting port is disposed more to the rear side than the rotation axis when the armrest body is in the horizontal position and in the vertical position.

5. The armrest according to claim 4 , wherein
the bracket includes the guide pin,
the armrest body includes the guide hole in an arc form with the rotation axis as a center of curvature, and
the guide hole guides the guide pin along with rotation of the armrest body.
