A headrest, especially for the seats in motor vehicles, in which the headrest is adjustable in its inclination against a constantly acting friction force; the adjustment is preferably stepless.

A head and neck rest for automobile or airplane seats comprises a headpiece and means for mounting the headpiece above the backrest of a seat. The mounting means include a sleeve member which is fixed within the backrest and an upright rod longitudinally traversing the sleeve. The sleeve and the headpiece are longitudinally adjustable on the rod for varying the position of height of the headpiece above the backrest. Spring means preferably consisting of rubber blocks are engaged between the inte...

A headrest at the backrest of a motor vehicle which is guided in the backrest by means of two mutually parallel support rods and is adjustable in its height; the support rods are slightly bent in the direction toward the back side of the backrest and are guided in substantially rectilinear guide members which include two guide bodies that are arranged at a distance from one another, surround the support rods and are slightly movable transversely to the longitudinal direction of the support rods.

The invention relates to an angularly adjustable head rest which is secured to the structure of the back rest of a motor vehicle seat. The head rest includes elements providing for lateral and tilting movement of the rest subsequent to uncoupling of elements provided adjacent one side of the rest.

An angularly and vertically adjustable head rest which is secured to a back rest of a motor vehicle seat. The heat rest may be immobilized in a desired height position by locking mechanism disposed entirely within and surrounded by the foam plastic cushion of the head rest. For height adjustment a first locking mechanism may be released by lateral pressure applied against one edge portion of the head rest and for tilting adjustment a second locking mechanism may be released by pressure applied t...

The invention relates to tiltable head rests for attachment to the back rest of an automobile and includes a vertically adjustable head rest supported on a housing which includes a telescopic brace adapted to be moved relative thereto and associated at the opposite free end with locking members permitting the tilting operation.

A headrest for a seat of a motor vehicle which is especially designed for protecting the seat occupant and a person sitting behind him from injuries especially in accidents. It comprises two complementary parts of foam plastic which are connected to each other and one of which is soft and resilient and forms the part on which the seat occupant may rest his head or neck, while the second part is of a harder and tough composition with a smooth outer surface and has embedded therein a curved reinfo...

A safety net pillow for the prevention of the snapping back of the head of a vehicle passenger having a net stretched on a frame, and leg means attached to the lower portion of the frame for detachably mounting the frame on the back of a seat of the vehicle in such a manner that the net stretched on the frame stands substantially upright.

A head rest is mounted on the upper end of a telescoping member. One element of this member is welded to a seat back frame in a strong, ladder-like construction. The close fit between the telescoping members provide a stability which enables the use of a simple spring biased detent as an indexing mechanism.

A motor vehicle body includes a seat, having a back-rest and a head-rest mounted on the back-rest, and means effective, upon engagement therewith by an occupant of the seat moving in response to the effect upon him of a predetermined deceleration of the vehicle body, to transmit a loading developed by the mass inertia of the occupant's body to the head-rest. The head-rest is thereby moved forward and energy absorber means secured between the head-rest and an anchorage on the body resist the forw...
