摘要

#CMT# #/CMT# The frame has standing legs (A, B), and a support unit (C) that connects the standing legs. The legs have side pieces (3, 3`, 4, 4`) that are connected at rotatable joints (8, 8`, 9, 9`) using connecting units (5, 5`). The side pieces (3, 3`) are connected at a cross bar (1) and the side pieces (4, 4`) are connected at rotatable joints (7, 7`). The cross bar is connected at the joints (7, 7`) such that connecting straight lines of the joints (8, 8`, 9, 9`) are parallel to the connecting units and the connecting straight lines of the joints (6, 6`) are parallel to another cross bar. #CMT#USE : #/CMT# Used for a vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The frame is designed in such a manner that it can be automatically held in a fixed position transverse to a seat surface in an automatic and stable manner, and enables efficient shifting of a wheel or ski operation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a tiltable frame in a neutral and rotatable position.
