The invention relates to a catch fitting (1) of an adjustable back rest or support of a piece of furniture, especially a piece of furniture for sitting or lying down. Said fitting comprises a connection plate (2) and a stop notch plate (3) that is pivotably connected to the connection plate and can be locked in various angular positions. Said stop notch plate comprises a toothing (8) which is concentrically arranged in relation to the axis (6) of the articulation, a locking device (4) which is rotatably mounted on the connection plate (2) engaging with said toothing in the catch position. Said locking device (4) is held by a spring (5) in the released position and is acted upon by the same spring (5) in the engaged position. The aim of the invention is to keep the structural dimensions to a minimum, while ensuring a high holding force and an engagement adjustment region which is as large as possible. To this end, an abutment cam (10) is simply provided on the stop notch plate (3) for releasing the locking device (4) by co-operation with a release lug (12), and the locking device (4) is provided with an engaging surface (11) which co-operates with the toothing (8) for the engagement. |
