Abstract
An active head restraint arrangement comprising a head restraint cushion, at least one head restraint post and head restraint post guide connecting said head restraint cushion to the interior of said passenger seats; and a flip-up assembly associated with said head restraint post beneath said head restraint cushion. Upon activation by rear impact, the flip-up assembly flips upward and forward to protect an occupant's head and neck from injury. Since this active head restraint arrangement utilizes a flip-up motion, the head restraint has a lower initial height that is dynamically increased upon activation. This feature allows the head restraint to be smaller allowing an occupant to have a better view around the head restraint.
Claims9
A head restraint arrangement for a vehicle seat, the head restraint arrangement comprising:
- a head restraint post associated with the vehicle seat;
- a flip-up assembly including a lower flip-up member attached to the head restraint post, a middle flip-up member connected to the lower flip-up member, and a top flip-up member pivotally connected to the middle flip-up member;
- and
- a head restraint cushion connected to the top, middle, and lower flip-up members;
- wherein the top flip-up member and corresponding head restraint-cushion are adapted to move from a deactivated position in which the top flip-up member and corresponding head restraint cushion extend in a substantially horizontal position away from a head of an occupant to an activated position in which the top flip-up member and corresponding head restraint cushion are pivoted to a substantially vertical position above the middle flip-up member to support the head of the occupant.
