Head restraints (also called headrests) are an automotive safety feature, attached or integrated into the top of each seat to limit the rearward movement of the adult occupant's head, relative to the torso, in a collision — to prevent or mitigate whiplash or injury to the cervical vertebrae. Since their mandatory introduction in the late 1960s, head restraints have prevented or mitigated thousands of serious injuries.

In the case of a head restraint which is connected to the backrest (5) of a vehicle seat, a padded segment (9) which can be changed in position relative to the basic body (1) of the head restraint can be shifted, in the event of an accident, under the action of a force-generating device from the use position toward the seat occupant's head (10) into a safety position and can be locked therein by means of a fixing device. According to the invention, the fixing device comprises a telescope (11) which, on the one hand, is supported on the basic body (1) and, on the other hand, is connected to the shiftable padded segment (9), it being possible for the resetting forces (FR) which act on the padded element to be introduced into the telescope in a direction deviating from the telescope axis (X).

A headrest assembly that is rotatable to various positions includes a support defining a horizontal axis. A shell is rotatably mounted to the support. Notches are disposed on the support, and each notch is associated with one of the positions. A lever is mounted to the shell and has a locking portion rotatable about the pivot axis and partially disposed in one of the notches to prevent movement of the shell. An actuator is mounted to the shell and rotates the locking portion of the lever about a pivot axis in a direction transverse to the horizontal axis. The actuator moves the locking portion out of one of the notches to allow the shell to rotate about the horizontal axis. Furthermore, the actuator moves the locking portion into one of the notches to prevent the shell from rotating about the horizontal axis.

Head rest device
InactiveUS20060006709A1Reduce rigidityReliable holdBack restsPedestrian/occupant safety arrangementRear-end collisionBowden cable
When a pressure receiving plate provided at a seat back moves to a rear side of a vehicle body when a vehicle is collided from behind, a Bowden cable transmits movement of the pressure receiving plate to a headrest ascending mechanism as a tensile load, thereby quickly ascending a headrest to reliably hold a head of an occupant. The Bowden cable transmits only the tensile load, and hence the Bowden cable is not buckled. Reduction in weight is made possible as compared with the case using a rod for transmitting a compression load. Since the Bowden cable is light, it is not required to unreasonably place the pressure receiving plate at a position near the headrest ascending mechanism for reduction in weight, and hence the pressure receiving plate can be placed at the optimal position where a sufficient driving force is obtained at the time of collision. Thus, a headrest is ascended with favorable responsiveness upon a rear-end collision of a vehicle while using a thin transmission member with low rigidity.

Headrest-mounted monitor
InactiveUS7044546B2Low risk of injuryVehicle seatsTelevision system detailsHead restraintElectrical and Electronics engineering
A monitor adapted for mounting in an automobile headrest is provided. A screen structure of the monitor is pivotable about an upper edge thereof, such that the monitor occupies little volume within the headrest. A viewing angle of the screen structure is independently adjustable by a viewer, such that the viewer can continuously select the optimum viewing angle with changing conditions inside the automobile. The screen structure automatically retracts into a housing when struck. Thus, the monitor poses little risk of injury to passengers. The housing of the monitor is attachable to the headrest with screws, which provides a very sturdy connection and reduces the chances of the housing becoming detached from the headrest during a vehicle collision. The hinged connection between the screen structure and the housing is preferably constructed of interconnected components made from sturdy materials, such as metals. Hinge components are optionally secured with metal fastening members and fastening apertures made of metal and strong plastics. The hinges are thus unlikely to break during a vehicle collision.
