Seat headrest mounting

Abstract

A headrest mounting for a seat, e.g,. for a motor vehicle, includes a mounting member ( 15 ) fitted in the seat backrest and affording an upwardly-open passage ( 21 ) for sliding reception of a downwardly extending headrest post ( 13 ); a locking member ( 25 ) extending transversely of the passage and having an opening ( 27 ) through which the post extends; spring means ( 31 ) biasing said locking member to become more inclined from the perpendicular to the longitudinal axis of the post, so boundaries of said opening frictionally grip the post, and release means ( 23, 41 ) for causing the locking member to be oriented more nearly perpendicular to the longitudinal axis of the post to release the post for longitudinal movement within said passage.

1 . A mounting member adapted to be fitted in a seat backrest and affording an upwardly-open passage for sliding reception of a downwardly extending headrest post; further comprising a locking member extending transversely of the passage and having an opening through which the post extends; spring means biasing said locking member to become more inclined from the perpendicular to the longitudinal axis of the post, so boundaries of said opening frictionally grip the post, and release means for causing the locking member to be oriented more nearly perpendicular to the longitudinal axis of the post to release the post for longitudinal movement within said passage.  
     
     
         2 . A mounting member according to  claim 1  wherein the locking member is an element of sheet metal.  
     
     
         3 . A mounting member according to  claim 2  wherein the locking member is resilient having the spring means integral therewith.  
     
     
         4 . A mounting member according to any one of  claims 1  to  3  wherein the locking member is disposed in a lower part of the mounting member.  
     
     
         5 . A mounting member according to  claim 4  wherein said release means comprises a manually operable release member provided in an upper part of the mounting member and connected to the locking member by transmission means.  
     
     
         6 . A mounting member according to  claim 5  wherein said transmission means is of plastics material and integral with the release member.  
     
     
         7 . A mounting member according to  claim 6  wherein said transmission means comprises a pull rod member.  
     
     
         8 . A mounting member according to  claim 7  wherein the release member includes a part movable generally in the direction of the length of the headrest post.  
     
     
         9 . A mounting member according to any one of  claims 5  to  7  wherein said release member includes a part movable transversely to the length of the headrest post.  
     
     
         10 . A seat comprising two mounting members for receiving two spaced parallel headrest posts, and wherein one of said mounting members is as claimed in  claim 1 .  
     
     
         11 . A seat according to  claim 10  wherein the other mounting member comprises releasable means for holding the respective headrest post captive to the mounting member.  
     
     
         12 . A seat according to  claim 10  or  claim 11  and having a headrest engaged thierewith.
