Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seat device for a vehicle that is equipped with a function to maintain the seated position of an infant, and in particular, the rotation mechanism of the infant holder saves layout space for interior equipment. It is installed in an improved seat system that does not cause pressure.

[Conventional technology]

Generally, a vehicle seat device has a structure in which a seat cushion is placed on the floor of a vehicle interior, and a seat bank is provided upright at the rear end of the seat cushion. However, when an infant is seated on this seat device, there is a risk that the infant may fall from the seat for some reason, such as the vehicle suddenly starting or stopping, or the infant moving around.

For this reason, various seat devices for vehicles have been proposed in the past that are capable of maintaining the seated posture of an infant. One example is shown in Japanese Utility Model Application Publication No. 54-18827, in which a horizontally extending child protection part is adjacent to or fitted as part of a seat cushion or seat bank. In other words, while providing it integrally,
Side support parts are provided on both sides of the seat cushion or seat back to rotatably support both ends of the child protection part, and when the child is seated, the child protection part is rotated and positioned in front of the child to protect the child. The lateral support portion prevents the infant from leaning forward, and the lateral support portion prevents the infant from leaning sideways.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional vehicle seat device, the child protection part is rotatably supported by the side support parts on both sides of the seat upholstery or the seat back.

The overall width of the seat system increases by the width of the rotating mechanism parts such as covers and locks. Especially when supporting the child protection part on the seat cushion, the layout space for interior equipment such as door trims and parking brakes should be There is a problem in that the width of the rotating mechanism parts is limited.

In view of these conventional problems, the present invention aims to provide a vehicle seat device that can secure a layout space for interior accessories such as a door trim and a parking brake.

[Means for Solving the Problems] Therefore, the vehicle seat device according to the present invention comprises a seat cushion body and an infant holder provided so as to be accommodated in the seat cushion body, and the infant holder is attached to the seat cushion body. The seat cushion is characterized in that a rotation mechanism rotatably supported by the cushion body is disposed within the seat cushion body.

Here, the rotation mechanism in the present invention includes a support bracket support frame, a lock mechanism, an unlock mechanism, etc.
The rotating mechanism can be placed in the center of the seat cushion body, at the bottom of the side edges, or even further below the cushion body, in other words, when the infant holder is accommodated, the rotating mechanism can Includes positions that do not protrude in either direction.

[Effect]

In this invention, since the infant support body is supported by the rotation mechanism disposed within the seat cushion main body, the rotation mechanism parts do not protrude to the side of the seat cushion as in the conventional case. In addition, it is possible to secure layout space for door trims, parking brakes, etc. on the sides of the seat cushion.
