Abstract

An armrest described herein includes an arm-side wire harness including an electric wire and an arm-side connector that is on an end of the electric wire and is to be coupled to a seat-side connector mounted on a seat. The armrest further includes an arm body member including an electric wire routing cavity in which the electric wire of the arm-side wire harness is arranged and a seat-side wall that is to be arranged opposite a seat frame of the seat. The arm body member is to be fixed to the seat frame while the seat-side wall being opposite the seat frame. The seat-side wall includes a connector insertion hole through which the arm-side connector can be inserted. The arm body member includes an operation hole that is continuous from the connector insertion hole via an arrangement section of the electric wire routing cavity.

First claim

What is claimed is:

1. An armrest comprising:
an arm-side wire harness including an electric wire and an arm-side connector that is on an end of the electric wire and is couplable to a mount member-side connector mounted on a mount member; and
an arm body member including an electric wire routing cavity in which the electric wire of the arm-side wire harness is arranged and a mount member-side wall that is to be arranged opposite the mount member, the arm body member to be fixed to the mount member while the mount member-side wall is opposite the mount member, wherein
the mount member-side wall includes a connector insertion hole through which the arm-side connector is insertable,
the arm body member includes an operation hole that is continuous from the connector insertion hole via the electric wire routing cavity,
the operation hole of the arm body member is open in a direction opposite from the mount member, and
the armrest further includes a cover body that covers the operation hole.

2. The armrest according to claim 1 , wherein the cover body is part of a cover that is attached to the arm body member to close the operation hole.

3. The armrest according to claim 1 , wherein when the arm body member is fixed to the mount member, the mount member-side connector and the arm-side connector that are coupled are inserted in the connector insertion hole.

4. The armrest according to claim 1 , wherein the electric wire having a length including a coupling stroke length necessary for coupling the mount member-side connector and the arm-side connector is arrangeable in the electric wire routing cavity.

5. A seat with an armrest comprising:
the armrest according to claim 1 ; and the mount member, wherein
the mount member is the seat, and
the mount member-side connector is fixed to the mount member so as to face the connector insertion hole when the arm body member is fixed to the mount member.

6. The seat with the armrest according to claim 5 , wherein
the arm body member is pivotable around an axis extending from the mount member to the arm body member, and
the electric wire having an extra length necessary for pivoting the arm body member is arrangeable in the electric wire routing cavity.
