Fitment for convertible seat or recliner with seat and backrest

摘要

The scissors-link (10) with three scissor joints is positioned between the scissor joint A and the seat (3) attachment (25). The scissors link has two relative fixed points on the four-bar linkage (4). The fixed point is on or near the link joint A in the top arm (8) of the four-bar linkage, in the form of a top scissor-joint of the scissors-link. The other fixed point is in a bearing point C in the top arm of the four-bar linkage, and is in the form of a scissor joint I of the scissors link. The seat attachment is joined to a strut (17) of the scissors link. A locking lever (31) is positioned on the bottom scissors joint opposite the link joint A or movably mounted on the strut (12) between the bottom strut joint and the bearing point C.
