Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to vehicle seats (particularly automobile seats), and more specifically, the present invention relates to a vehicle seat (particularly an automobile seat). Rotate 180 degrees to the car floor,
This relates to a seat in which the bottom surface of the seat cushion can be used as a cargo platform.

(Prior art and its problems) In this type of automobile seat (third seat), the seat bag has a longer overall length than the seat cushion, so when the seat bag is laid down on the seat cushion, the seat cushion The top of the seat bag protrudes from the front end, and this protrusion allows the seat cushion to be connected to the seat bag, and the seat cushion to be held together with the seat bag.
Since the passenger seated in the front third seat cannot be accommodated in the low floor of the vehicle where the feet rest, the seat back is divided into an upper seat back part and a lower seat back part, and the stay of the headrest is passed through the upper seat back part. There is one in which the upper seat back part is attached to the lower seat back part together with the headrest.

Therefore, when using the seat as a loading platform,
When the upper seat back part is removed from the lower seat back part together with the head rest, the lower seat back part is laid down on the seat cushion, and rotated 180 degrees forward together with the seat cushion, the lower seat back part is shorter in overall length than the seat cushion. It can be stored on the front floor of the vehicle, and the bottom of the seat cushion can be used as a loading platform along with the vehicle floor where the seat cushion is installed. In addition, when used as a seat, the upper seat back is attached to the lower seat back with the head rest using the stay of the head rest, but the height position of the head rest is adjusted according to the position of the occupant's head. When the headrest is raised, since there is no locking mechanism for locking the upper seatback part to the lower seatback part, the upper seatback part also rises together with the stay of the headrest, and the occupant can lift the raised upper seatback part by hand. This was very troublesome as the seat had to be lowered to the lower seat back side.

This invention was made in view of this point, and when the headrest is raised, the upper seat back part is locked onto the lower seat back part,
To provide a vehicle seat in which an upper seat back part does not rise together with a headrest.

(Means and effects for solving the problem) The vehicle seat according to this invention has belt members provided on the lower surface of the upper seat back portion and the upper surface portion of the lower seat back portion, and both ends of one of the belt members are fixed. A gap is formed between this belt member and the surface part, one end of the other belt member is fixed, and the other end is removably attached to the surface part, so that when adjusting the height of the headrest, the lower surface of the upper seat back part is fixed. The upper seat back part is locked to the lower seat back part by locking the belt member on the lower seat back part and the belt member on the upper surface part of the lower seat back part, and the movement of the upper seat back part can be restricted.
