Adjustable seat structure in railway passenger carriage - has guide rails backrest control and frame guide lugs in angled sections

摘要

The seating assembly, esp. in a railway coach, has a frame which can be pre-set by means of a rail guiding system, with back-rest unfolding in the direction of horizontal extension. For this, use is made of control lugs on rail guides below the frame, with track diverging from that of the backrest pivotal point as in 2041787. The guide rails for the backrest control lugs and those for the frame guide lugs are divided into separate sections set at an angle to one another, so that the transitional points occuring in the angle apexes form retainer troughs for the lugs.
