Armstödskonstruktion för stolar

摘要

The input arm (5) is joined via a link piece to a support (14) vertically movable along a guide piece (17) that contains a number of seats interspaced in the height direction for receiving a spring-loaded catch. This catch can be moved in a sideways direction relative to the input arm, between an outer end position where part of the catch is engaged with a chosen seat, and an inner end position where the catch is freely movable between different seats.
