Benefits of technology
The present invention relates to inserts for vehicle seat head restraints that can reduce the risk of head, neck, and spinal injuries during rear impact events or sudden deceleration events. The technical effects of the invention include reducing the energy stored in the foam of the seat head restraints during a rear impact event and providing a more comfortable and aesthetically pleasing surface for supporting the occupant's head. The invention also includes various methods for attaching the head restraint to the seat back and a compressible pad member for added comfort.
Problems solved by technology
Occupants of motor vehicles have long suffered head, neck and spinal injuries during events such as rear vehicle impact or sudden deceleration.
In a rear impact event, the occupant's head contacts the top of the vehicle head restraint with sufficient force to result in a significant deflection of the foam.
As such, when the rear collision event has ended, the energy stored within the foam is released into the occupant's head, which causes the occupant's head to move rapidly forward possibly causing further injury to the vehicle occupant.

Abstract
A head restraint assembly for a vehicle seat has a head restraint post adapted to be mounted to the vehicle seat. A support member is coupled to the head restraint post. The support member having a plurality of attachment receptacles to mount the head restraint post to one of the plurality of attachment receptacles. A compressible pad member is mounted to the support member. A convex outer surface provides support for a head of an occupant. The support member is mounted to head restraint post at one of the plurality of attachment receptacles positions the compressible pad at a distance from the convex outer surface.
Description
BACKGROUND[0001]1. Technical Field[0002]Multiple embodiments relate to inserts for vehicle seat head restraints.[0003]2. Background Art[0004]Occupants of motor vehicles have long suffered head, neck and spinal injuries during events such as rear vehicle impact or sudden deceleration. Typically, a vehicle head restraint is constructed with compressible foam surrounding a head restraint post. In a rear impact event, the occupant's head contacts the top of the vehicle head restraint with sufficient force to result in a significant deflection of the foam. The magnitude of neck deflection increases as the head further compresses the foam. Furthermore, because the foam is sufficiently resilient, the energy imparted to the foam by the occupant's head is mostly stored and not dissipated. As such, when the rear collision event has ended, the energy stored within the foam is released into the occupant's head, which causes the occupant's head to move rapidly forward possibly causing further in...
