IMPROVEMENTS IN OR RELATING TO VEHICLE SEAT BACKS

摘要

In the field of vehicle seats there is a need for an improved vehicle seat back tilt adjustment assembly that allows a user selectively to make small or large adjustments to the inclination of a vehicle seat back. A vehicle seat back tilt adjustment assembly comprises a guide member (22) securable to a vehicle body; and an intermediate mechanism (26) moveably coupled to the guide member (22). The intermediate mechanism (26) includes first and second locking elements (28, 30). The first locking element (28) is moveable between a first configuration in which it is engagable with a vehicle seat back (14) to secure the seat back to the intermediate mechanism (26) and a second configuration in which the seat back (14) is disengagable therefrom to allow the seat back to move independently of the intermediate mechanism. The second locking element (30) selectively engages the guide member (22) to secure the position of the intermediate mechanism (26) relative to the guide member.
