Claim 4

A headrest assembly according to claim 2, in which the range of adjustment of the sleeve means within the guide means accommodates dimensional variations from the fixed bracket to the upper surface of the cushioned seat back resulting from design variations in cushion thicknesses on different model seats.

Claim 5

A headrest assembly according to claim 2, in which: the fixed bracket means inCludes a detent means engaged with the support posts to hold the headrest member in any one of a plurality of selected raised or lowered positions relative to the upper surface of the cushioned seat back.

Claim 6

A headrest assembly according to claim 4, in which: the detent means comprises a resilient latch device; and the support posts have a plurality of latch device engaging notches at the lower end thereof; and the resilient latch device being selectively engaged with any one of said notches to yieldably hold the headrest member in any one of a plurality of selected raised or lowered positions relative to the upper surface of the cushioned seat back.

Claim 7

A headrest assembly according to claim 5, in which: the lowermost of the plurality of support post notches and the resilient latch device coact to resist withdrawal of the support post from the guide means and sleeve means.

Claim 8

A headrest assembly according to claim 1, in which: the fixed bracket means includes detent means engaged with the support post to hold the headrest member in any one of a plurality of selected raised or lowered positions relative to the upper surface of the cushioned seat back.

Claim 9

A headrest assembly according to claim 7, in which: the detent means comprises a resilient latch device; the support post has a plurality of latch device engaging notches at the lowered end thereof; and the resilient latch device is selectively engaged with any one of said notches to yieldably hold the headrest member in any one of a plurality of selected raised or lowered positions relative to the upper surface of the cushioned seat back.

Claim 10

A headrest assembly according to claim 8, in which: the lowermost of the plurality of support post notches and the resilient latch device coact to resist withdrawal of the support post from the guide means and sleeve means.

Claim 11

A headrest assembly for a cushioned seat back, comprising: a cushioned headrest member attached to one end of a support post; a fixed bracket mounted within said seat back having a longitudinally extending channel therein; an elongated sleeve comprising a channel member having an escutcheon at the upper end thereof; the sleeve channel member being telescopically adjustably received within the bracket channel; the engagement of the escutcheon with the upper surface of the seat back cushion controlling the depth of penetration of the sleeve channel member into the bracket channel; the sleeve channel member and the bracket having interlocking latch means comprising a deflectable latch portion on the sleeve channel member and keeper elements on the bracket extending longitudinally of the direction of insertion of the sleeve in the bracket; the sleeve channel member and the bracket channel coacting to telescopically support the headrest support post therein; and the sleeve channel member being locket locked to the bracket by deflection of the latch portion into engagement with one of said keeper elements by the support post upon telescopic insertion of the latter into the sleeve channel member and bracket channel.

Claim 12

A headrest assembly for a cushioned seat back, comprising: a cushioned headrest member attached to one end of a support post; a fixed bracket mounted within said seat back having a longitudinally extending channel therein; an elongated sleeve comprising a channel member having an escutcheon at the upper end thereof; the sleeve channel member being telescopically adjustably received within the bracket channel; the engagement of the escutcheon with the upper surface of the seat back cushion controlling the depth of penetration of the sleeve channel member into the bracket channel; the sleeve channel member and the bracket having interlocking latch means comprising a deflectable latch portion on the sleeve channel member and keeper elements on the bracket extending longitudinally of the direction of insertion of the sleeve in the bracket; the sleeve channel member and the bracket channel coacting to telescopically support the headrest support post therein; and the sleeve channel member being locket locked to the bracket by deflection of the latch portion into engagement with one of said keeper elements by the support post upon telescopic insertion of the latter into the sleeve channel member and bracket channel.

Claim 13

A A headrest assembly according to claim 10, in which: the range of adjustment of the sleeve channel member within the bracket channel accommodates dimensional variations from the fixed bracket to the upper surface of the cushioned seat back resulting from design variations in cushion thicknesses on different model seats.

Claim 14

A headrest assembly according to claim 11, in which: the fixed bracket supports detent means engageable with the support post to hold the headrest member in any one of a plurality of selected raised or lowered positions relative to the upper surface of the cushioned seat back.

Claim 15

A headrest assembly according to claim 10, in which: the detent means comprises a resilient latch device engageable with any one of a plurality of notches on the support post to hold the headrest member in any one of a plurality of selected raised or lowered posItions relative to the upper surface of the cushioned seat back.

Claim 16

A headrest assembly according to claim 13, in which: the lowermost of the plurality of support posts notches and the resilient latch device coact to resist withdrawal of the support posts from the bracket and the sleeve.
