Problems solved by technology

[0004] However, in Patent Document 1, the rotation of the movable member in the unfolded position in the opposite direction, that is, in the storage direction, is restricted by the air bag.
Therefore, for example, if the air bag is compressed by an external force such as when a vehicle collides, it may become difficult to maintain the movable member at the deployed position.

Embodiment Construction

[0041] Hereinafter, an embodiment of a vehicle seat device will be described.

[0042] Such as figure 1 As shown, a vehicle seat 1 is configured to include a seat cushion 2 placed on a vehicle floor, and a seat back 3 tiltably (rotatably) supported on a rear end portion of the seat cushion 2 . The seat back 3 allows adjustment of the inclination angle with respect to the seat cushion 2 by a reclining mechanism (not shown) provided around its axis. The seat cushion 2 and the seat back 3 respectively constitute a seating portion and a backrest portion of a person who basically sits on the seat 1 . The state of the seat 1 at this time is called a normal mode. In addition, the seat 1 accommodates the child seat 10 in a deployable manner.

[0043] That is, if figure 2 as well as image 3 As shown in (a) and (b), the seat back 3 has a back main body 4 and a movable seat cushion 5 . The backrest main body 4 has a pair of side support portions 4a protruding forward from the low...

Abstract

The present invention provides a vehicle seat device capable of more firmly holding a movable member in a deployed position. The vehicle seat device includes: a backrest base (32) arranged on the backrest of a seat; a seat cushion base member (33) rotatably connected to the backrest base (32); and a pair of stopper parts disposed to abut the backrest base (32) and the seat cushion base member (33). The movable member rotates from a storage position and the rotation of the movable member is restricted at a deployment position so that a seat mode is changed. The seat cushion base (33) rotates from the storage position to the unfolding direction (D7), and the rotation is limited at the unfolding position where the two limiter parts abut against each other, so that the seat mode is changed. The vehicle seat device is provided with: a first air bag that rotates a seat cushion base (33) from a stowed position to an expanded position by pressing the backrest base (32) and the seat cushion base (33) in association with expansion; and a first clutch mechanism (65) that permits rotation of the seat cushion base (33) in the deployment direction (D7) and restricts rotation of the seat cushionbase (33) in the storage direction (D8) in the deployed position.

Description

technical field [0001] The present invention relates to a vehicle seat device capable of changing a seat mode. Background technique [0002] Conventionally, as such a vehicle seat device, for example, the vehicle seat device described in Patent Document 1 is known. This vehicle seat device is configured to include: a base member (back base) provided on the seat back; a movable member (wing) rotatably connected to the base member; a pair of stopper portions where the movable member abuts against each other; and an air bag interposed between the base member and the movable member. The seat device for a vehicle is rotated in one direction, that is, the deployment direction by the movable member relative to the base member, and its rotation is restricted at the deployment position where the two stopper parts abut against each other, so that the seat mode changes from the normal mode to the sitting mode. Child mode change for deploying the child seat on the seat. In addition, ...
