Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a seat device for a vehicle that is equipped with a function to maintain the sitting position of an infant, and in particular to an infant holder that can reliably maintain the seating position of an infant. It is related to shape improvement.

[Conventional technology]

2. Description of the Related Art 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 bag is provided in an upright manner 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. As an example, for example,
No. 18827 discloses a device in which a horizontally extending child protection portion is provided as part of the seat cushion or seat bag, adjacent to or fitted into the seat cushion, i.e. integrally with the seat cushion or the seat bag; Side support parts are provided on both sides of the seat back to rotatably support both ends of the infant protection part, and when the infant is seated, the infant protection part is rotated and positioned in front of the infant, and The device prevents the infant from leaning forward, and the lateral support portion prevents the infant from tipping to the side.

[Problem that the invention attempts to solve]

By the way, considering the situation in which an infant falls from a seat, when an infant falls from a seat, there are not only cases where the infant falls from the seat by leaning forward or sideways, but also cases where the infant falls forward along the top surface of the seat cushion. It is possible that the vehicle may slip. However, conventional vehicle seat systems do not take this point into consideration, and due to their structure, infants may slip forward between the child protection part and the seat cushion.
There are concerns that the so-called submarine phenomenon will occur.

In view of these problems, this invention aims to provide a seat device for a vehicle that can securely maintain the seated position of an infant by preventing the infant from not only leaning forward and sideways but also from sliding forward. It is something.

[Means for solving problems]

Therefore, in the vehicle seat device according to the present invention, the seat cushion is constituted by a seat cushion main body and an infant holder provided to fit into the seat cushion body, and the infant holder is connected to a horizontal portion extending in the width direction. A support part, a self-supporting leg part extending in a substantially vertical direction from approximately the center thereof, and a side support part extending in a substantially vertical direction from both ends of the horizontal support part and provided rotatably with respect to the horizontal support part. The free-standing legs are rotatably supported by the seat cushion body, and when the child is seated, the child support body is erected by rotating around the ends of the free-standing legs, and the horizontal supporting portion is The self-supporting legs are positioned between the infant's legs, and the lateral support portions are rotated to be positioned to the side of the infant.

[Effect]

In this invention, when an infant is seated, the infant holder is raised up so that the horizontal support section is positioned in front of the infant, and the lateral support section is rotated to be positioned to the side of the infant. and lateral tilting is prevented by the horizontal support or lateral support, and since the independent legs are positioned between the infant's legs, forward sliding of the infant is prevented by the independent legs. As a result, the sitting posture of the infant is reliably maintained.
