Abstract

The vehicle occupant restraining device includes: a three-point seatbelt device adapted to restrain a vehicle occupant, who is seated at a vehicle seat, by a shoulder belt portion and a lap belt portion of a seatbelt; a rear side restraining portion configured to be disposed at a seatback of the vehicle seat, and spanning between left and right side frames of the seatback, the rear side restraining portion being in a slack state and convex toward a seat rear side; and a pulling device that, by pulling at least one end portion side of the rear side restraining portion, reduces slack of the rear side restraining portion.

Claims

1. A vehicle occupant restraining device comprising:

a three-point seatbelt device adapted to restrain a vehicle occupant, who is seated at a vehicle seat, by a shoulder belt portion and a lap belt portion of a seatbelt;

a rear side restraining portion configured to be disposed at a seatback of the vehicle seat, and spanning between left and right side frames of the seatback, the rear side restraining portion being in a slack state and convex toward a seat rear side; and

a pulling device that, by pulling at least one end portion side of the rear side restraining portion, reduces slack of the rear side restraining portion.

2. The vehicle occupant restraining device of claim 1, wherein the pulling device is a take-up device that pulls at least the one end portion side of the rear side restraining portion while taking-up at least the one end portion side onto a take-up shaft.

3. The vehicle occupant restraining device of claim 1, further comprising a vehicle seat,

wherein the rear side restraining portion is a belt member that is formed in an elongated shape and the belt member is disposed at an interior of the seatback of the vehicle seat.

4. The vehicle occupant restraining device of claim 3, wherein

the seatback has a seat pad that includes a pad main body portion that is adapted to support a back portion of the vehicle occupant from the seat rear side, and

an intermediate portion of the belt member is disposed at a seat rear side of the pad main body portion.

5. The vehicle occupant restraining device of claim 3, wherein

the seatback has a seat pad that includes a pad main body portion that is adapted to support a back portion of the vehicle occupant from the seat rear side, and

an intermediate portion of the belt member is disposed at a seat front side of the pad main body portion.

6. The vehicle occupant restraining device of claim 3, wherein

the seatback has a seat pad that includes a pad main body portion that is adapted to support a back portion of the vehicle occupant from the seat rear side, and

an intermediate portion of the belt member is embedded in the pad main body portion.

7. The vehicle occupant restraining device of claim 3, wherein

the seatback has a seat pad that includes a pad main body portion that is adapted to support a back portion of the vehicle occupant from the seat rear side, and a seat surface skin that includes a front surface skin that covers the pad main body portion from a seat front side, and

an intermediate portion of the rear side restraining portion is structured by the front surface skin.

8. The vehicle occupant restraining device of claim 3, wherein the belt member is disposed so as to be tilted in a direction opposite to a direction in which direction the shoulder belt portion is extended as seen in a seat front view.
