Abstract
An adjustable hinge for an automotive vehicle seat assembly having a backrest member and a seat member and actuatable to incline the backrest member and a seat member about a pivot axis to any of a plurality of adjusted positions. The hinge comprises a pair of substantially coaxial and relatively rotatable members in which non-parallel slots are formed. A control member is mounted for movement axially of the coaxial members and has a projecting pin member extending into the non-parallel slots. Axial movement of the control member causes the pin member to move through the slots to pivot the coaxial members about a pivot axis to tilt the backrest member to an adjusted position relative to the seat member.
Claims13
An adjustable hinge comprising a pair of elements, means pivotally connecting said elements for relative pivoting to a plurality of adjusted positions, said pivotal connecting means comprising a first member connected to one of said elements and a second member connected to the other of said elements, said first and second members being substantially coaxial and relatively rotatable about a pivot axis, means forming cam opening means in said one member defining a first path spaced from said pivot axis, means forming control opening means in said second member defining a second path spaced from said pivot axis different from said first path, a slider member mounted for movement axially of said first and second members, said slider member having projecting means extending into said cam opening means and into said control opening means, said projecting means being movable through said cam and control opening means in response to movement of said slider member axially of said first and second members to cause relative rotation between said first and second members to pivot said elements to said adjusted positions.
In a vehicle seat assembly having a seat member and a backrest member, mounting means mounting said backrest member on said seat member for adjustable pivoted movement about a pivot axis to a plurality of adjusted positions with respect to said seat member, said mounting means including a first member connected to said seat member and a second member connected to said backrest member, said first and second members being relatively pivotal about said pivot axis, means forming non-parallel slots in said first and second members, a control member mounted for movement axially of said first and second members, and pin means mounted on said control member and extending into said slots, said pin means being movable through said slots in response to movement of said control member axially of said first and second members to cause relative pivotal movement between said first and second members to pivot said backrest member to an adjusted position.
