Description

  The present invention relates to a vehicle seat including an illumination device (a device having a cylindrical holding member and an illumination lamp).

As this type of vehicle seat, a vehicle seat having a seat cushion, a seat back, and an illumination device is known (see Patent Document 1).
The illumination device includes a substantially rectangular illumination lamp, an arm portion (corresponding to a holding member), and a connecting portion. The arm portion is a member (a member that can be expanded and contracted) in which a plurality of pipe members are slidably connected to each other in the length direction. The connecting portion is a bendable cylindrical material (for example, a thin cylindrical covering portion made of rubber and a cylindrical material made of a spiral spring material in the covering portion), and connects the tip of the arm portion and the illuminating lamp.
In the known technique, the base of the arm part is connected to the armrest part of the seat cushion (the part protruding upward on the seat side part) so as to be able to be tilted. Then, a storage recess is provided on the rear side of the seat so that the arm part in the rearward fall state can be stored together with the illumination lamp.
Therefore, the arm part is erected from the armrest part, and the hand of the occupant is illuminated with an illumination light. At this time, the direction of the illuminating lamp is adjusted by appropriately bending the connecting portion in the middle of its length direction. When the use of the illuminating device is finished, the arm portion is tilted backward and is housed in the housing recess together with the illuminating lamp (the configuration is not always exposed).

By the way, in this type of seat configuration, when the passenger gets on and off the vehicle or moves inside the vehicle, the occupant may be held by the seat and hold the posture.
In view of the convenience of the seat and the like, it is desirable to appropriately provide a member as a passenger's handle on the seat. However, the configuration tends to be complicated by increasing the number of parts of the sheet.
