Headrest, especially for seats in motor vehicles

Claim 2

The combination of a headrest and an angularly adjustable attachment means for attaching the headrest to a car seat or the like, wherein said attachment means comprises support rod means connectable to the car seat for supporting the headrest in a spaced position with respect to said car seat and constantly effective friction force means adapted to resist changes in the angular orientation of said headrest.

Claim 3

The combination according to claim 1, characterized in that said attachment means is adapted to be steplessly or continuously adjustable.

Claim 4

The combination according to claim 2, characterized in that the friction force means includes a spring.

Claim 5

The combination according to claim 2, characterized in that said attachment means further comprises, shaft means non-rotatably connected to the support rod means, said headrest being rigidly connected to a tubular member disposed about said shaft means, and spring means positioned so as to force at least one conical pressure member into contact with an expanding body means positioned within the tubular member and about the shaft means.

Claim 6

The combination according to claim 4, characterized in that the expanding body means is a slotted sleeve.

Claim 7

The combination according to claim 2, characterized in that at least one conical pressure member is arranged on the inside of a tubular member securely connected with the headrest, said conical pressure member acting on an expanding body means non-rotatably connected with the support rod means.

Claim 8

The combination according to claim 6, characterized in that said expanding body means is a slotted expanding sleeve.

Claim 9

The combination according to claim 2, characterized in that at least one expanding body means made from elastic material which is subjected to a constant spring force and is mounted on a shaft non-rotatably connected with the support rod means, is arranged on the inside of a tubular member securely connected with the headrest.

Claim 10

The combination according to claim 8, characterized in that said expanding body means is under the constant force of a spring, and pressure discs arranged between said spriNg and the expanding body means.

Claim 11

The combination according to claim 1, characterized in that the friction force means include a spring.

Claim 12

The combination according to claim 1, characterized in that said attachment means further comprises, shaft means non-rotatably connected to the support rod means, said headrest being rigidly connected to a tubular member disposed about said shaft means, at least one conical pressure member mounted on said shaft means, and constant spring force means positioned to force said conical pressure member against an expanding body member mounted on said shaft means.

Claim 13

The combination according to claim 11, characterized in that the expanding body means is a slotted sleeve.

Claim 14

The combination according to claim 1, characterized in that at least one conical pressure member is arranged on the inside of a tubular member securely connected with the headrest, said conical pressure member acting on an expanding body means non-rotatably connected with the support rod means.

Claim 15

The combination according to claim 13, characterized in that said expanding body means is a slotted expanding sleeve.

Claim 16

The combination according to claim 17, characterized in that at least one expanding body means made from elastic material is mounted on a shaft non-rotatably connected with the support rod means, said expanding body means being arranged on the inside of a tubular member securely connected with the headrest and spring means adapted to exert a constant spring force on said expanding body means.

Claim 17

The combination according to claim 15, characterized in that said expanding body means is under the constant force of a spring, and pressure discs are arranged between said spring and the expanding body means. 17 The combination of a headrest and an angularly adjustable attachment means for attaching the headrest to a car seat or the like, wherein said attachment means comprises a tubular member rigidly attached to the headrest, support rod means connectable to the car seat for supporting the headrest in a spaced position with respect to said car seat, and means provided internally of said tubular member to exert a constant frictional force on the internal walls of said tubular member.

Claim 18

The combination according to claim 11, characterized in that two oppositely facing conical pressure members are provided adjacent respective opposite ends of the shaft means for engagement respectively with two separate expanding body members mounted on said shaft means.

Claim 19

The combination according to claim 18, characterized in that said constant spring force means consists of a single coil spring surrounding said shaft means, the opposite ends of said spring being in engagement with the two respective conical pressure members.
