Abstract

A vehicular safety seat having a seat portion, a backrest provided with a pair of movably mounted arms having forward portions which, on severe vehicular impact, are driven inwardly under pressure of released gases to a body-restraining position adjacent the torso of an occupant of the seat and immediately over his thighs, at least one of said arms carrying adjacent the forward end thereof a folded air bag which is simultaneously inflated by said gases to provide a protective pillow between the chin and the thighs of the occupant which does not obstruct his vision. The pillow deflates and the arms are retracted to a nonprotective position immediately upon cessation of the impact, thereby affording unrestricted movement on the part of the seat occupant.

Claims

1. A vehicular safety seat for an individual passenger comprising, a seat portion, a back rest, a pair of arms movably mounted on opposite sides of the back rest and projecting therefrom in a generally forward direction at substantially the level of arm rests, and arm control means adapted to maintain the arms in a nonrestraining position under normal driving conditions and to move the arms into a body-restraining position adjacent the torso of the seat occupant and over his thighs when actuated by the flow of gases from a gas supply device as triggered by a sensor on impact of a predetermined force on the vehicle.

2. A seat as recited in claim 1, wherein a gas inflatable bag is carried adjacent a forward portion of at least one of the arms.

3. A seat as recited in claim 2 wherein the gas supply device is positioned within the seat and wherein the gases released therefrom on impact of the vehicle flow to the arm control means to actuate the movement of the arms to the restraining position as well as to the bag to inflate the same.

4. A seat as recited in claim 3 wherein both the arm control means and the pillow are provided with gas escape means permitting the pillow to deflate and the arms to be returned to the nonrestraining position as soon as the impact on the vehicle is over, thereby permitting an occupant of the seat to leave the same.
