Abstract

An armrest serves as an elbow rest of a seat device in a case where the armrest is tilted forward and serves as a backrest of the seat device in a case where the armrest is raised rearward. The armrest includes an armrest pad configured to elastically support a load applied to a backrest surface forming a part of a front surface of the seat device in a case where the armrest serves as the backrest, an armrest cover configured to cover the armrest pad, a protrusion that protrudes from the backrest surface of the armrest cover and abuts against an upper surface of a seat cushion of the seat device in a case where the armrest is tilted forward, and a cutout portion formed in a region that overlaps the protrusion of the armrest cover in a thickness direction of the armrest.

First claim

What is claimed is:

1 . An armrest configured to serve as an elbow rest of a seat device in a case where the armrest is tilted forward and serve as a backrest of the seat device in a case where the armrest is raised rearward, the armrest comprising:
an armrest pad configured to elastically support a load applied to a backrest surface forming a part of a front surface of the seat device in a case where the armrest serves as the backrest; an armrest cover configured to cover the armrest pad; a protrusion that protrudes from the backrest surface of the armrest cover and abuts against an upper surface of a seat cushion of the seat device in a case where the armrest is tilted forward; and a cutout portion formed in a region that overlaps the protrusion of the armrest cover in a thickness direction of the armrest.

2 . The armrest according to claim 1 ,
wherein the armrest is fitted into a recess of a forward-tiltable seat back of the seat device from a front side to serve as the backrest, and wherein the armrest is tilted forward together with the seat back in a case where the seat back is tilted forward to abut the protrusion against the upper surface of the seat cushion.

3 . The armrest according to claim 1 ,
wherein the protrusion is a strip-shaped band that serves as a gripper in a case where the armrest is tilted forward, wherein a resin plate that serves as a core material is inserted into the band, and wherein the cutout portion is formed in a region that overlaps the resin plate in the thickness direction of the armrest.

4 . The armrest according to claim 3 ,
wherein the band extends in a seat width direction, wherein two ends of the band are fixed to the armrest cover, and wherein the band overlaps the cutout portion in the thickness direction of the armrest over an entire region in an in-plane direction of the backrest surface.

5 . The armrest according to claim 1 ,
wherein the armrest pad includes:
a pad body; and
a laminated pad provided in a laminated manner on a side of the backrest surface relative to the pad body and softer than the pad body, and
wherein the cutout portion is formed to penetrate the laminated pad in the thickness direction of the armrest.

6 . The armrest according to claim 1 , further comprising a cup folder,
wherein the cutout portion is disposed at a position displaced toward a base end side of the armrest relative to the cup folder such that overlapping in the thickness direction of the armrest with the cup folder is avoided.
