Headrest for seat of vehicle

Claim 2

In a vehicle seat headrest unit of the type having a frame with a pair of spaced leg portions adapted for attachment to the seat and energy absorbing means spanning the frame for absorbing energy, the improvement comprising reinforcement means surrounding the frame and connecting said energy absorbing means to the frame, said reinforcement means having a plurality of segments, and said segments cooperating with said energy absorbing means in the absorbtion of a shock to said headrest unit.

Claim 3

The headrest according to claim 1, wherein said segments are hollow and rectangular in shape.

Claim 4

The headrest according to claim 2, wherein said segments have a wall in communication with and for supporting said energy absorbing means, said wall adapted to flex when a shock is imparted to said energy absorbing means thereby cooperating with said means in absorbing said shock.

Claim 5

The headrest according to claim 1, wherein said energy absorbing means is the same thickness as said reinforcement means.

Claim 6

The headrest according to claim 1, wherein said energy absorbing means is a foil.

Claim 7

The headrest according to claim 1, in which the energy absorbing means is placed at a distance from the top of the back of the seat so as to permit passengers of the vehicle, independent of their height, to rest their heads on the headrest without having to adjust it.

Claim 8

The headrest according to claim 1, in which the energy absorbing means and the reinforcement means are made of one piece of transparent and elastic material.

Claim 9

The headrest according to claim 1, in which the frame is exclusively formed out of elements with rounded sections so as to prevent said energy absorbing means and said reinforcement means from being torn or the passengers from being hurt.

Claim 10

The headrest according to claim 1, in which the frame is formed of a round bar of steel, bent in order to permit its fixation onto the seat.

Claim 11

The headrest according to claim 1, in which the frame is made of a hard injection moldable synthetic material having a high mechanical resistance.

Claim 12

A headrest for vehicle seats comprising: (a) a frame having a pair of spaced-apart leg portions (b) a reinforcement means surrounding said frame and having a plurality of rectangular, hollow segments, and (c) an energy absorbing means attached to a common wall of said segments, said wall of said segments beng adapted to flex when a shock is imparted to said energy absorbing means.

Claim 13

A headrest for vehicle seats comprising: (a) a frame having a pair of spaced-apart leg portions (b) a reinforcement means surrounding said frame and having a plurality of rectangular, hollow segments, and (c) an energy absorbing means attached to a common wall of said segments, said wall of said segments beng adapted to flex when a shock is imparted to said energy absorbing means.

Claim 14

The headrest in accordance with claim 11, wherein said common wall is the inner wall of said segments.

Claim 15

The headrest in accordance with claim 11, wherein said common wall is the outer wall of said segments.

Claim 16

The headrest according to claim 11, wherein said energy absorbing means is a foil.

Claim 17

The headrest according to claim 11, in which the energy absorbing means and the reinforcement means are made of one piece of transparent and elastic material.

Claim 18

The headrest according to claim 11, in which the frame is exclusively formed out of elements with rounded sections so as to prevent said energy absorbing means and said reinforcement means from being torn or the passengers from being hurt.

Claim 19

A headrest for vehicle seats comprising: (a) a frame having a pair of spaced-apart leg portions, (b) a reinforcement means surrounding said frame and having a plurality of hollow segments, each of said segments having upper members and lower members, said upper members comprising the outside periphery of said reinforcement means and said lower members comprising the inside periphery of said reinforcement means as it surrounds said frame, (c) an energy absorbing means attached to said lower members of said segments, said lower members adapted to flex when a shock is imparted to said energy absorbing means.

Claim 20

A headrest for vehicle seats comprising: (a) a frame having a pair of spaced-apart leg portions, (b) a reinforcement means surrounding said frame and having a plurality of hollow segments, each of said segments having upper members and lower members, said upper members comprising the outside periphery of said reinforcement means and said lower members comprising the inside periphery of said reinforcement means as it surrounds said frame, (c) an energy absorbing means attached to said lower members of said segments, said lower members adapted to flex when a shock is imparted to said energy absorbing means.
