摘要： Operation force required for pivot operation of a movable body can be set almost constant independent of variation in the angular position of the pivoting. A pivot mechanism (tumble mechanism (10A)) has a floor-side member (B) fixed to a predetermined position; a seat-side member (12) connected to the floor side member (B) by hinge coupling so as to be pivotable in a predetermined angle range; and a torsion spring member (14)provided to urge the seat side member (12)in the opposite direction to gravity that acts on the seat side member (12). The pivot mechanism is constructed such that weight moments about a pivot center (13a) acting on the seat-side member (12) as the pivot mechanism move varies. The torsion spring member (14) has an urging the section (14b) for urging the seat seat member (12) and a support section (14a) that is supported by the floor side member (B). The support section (14b)is disposed at a position between a pivot track of the urging section (14b) produced by the pivoting of the pivot mechanism and the pivot center (13a).

摘要： It is intended that an operation force required for pivoting a movable body can be maintained substantially constant regardless of an angular position of pivot of the movable body.A pivot mechanism (a tumble mechanism 10A) includes a floor-side member B fixed to a desired position, a seat-side member 12 coupled to the floor-side member B by hinge coupling so as to be pivotable within a predetermined angle range, and a torsion spring member 14 arranged to bias the seat-side member 12 in a pivot direction opposite to the gravitational force acting on the seat-side member 12. The pivot mechanism is constructed such that gravitational moments about a pivot center 13a acting on the seat-side member 12 can be changed depending on pivoting thereof. The torsion spring member 14 has an biasing section 14b for biasing the seat-side member 12 and a support section 14a supported on the floor-side member B. The support section 14b is positioned at a position between a pivot trajectory of the biasing section 14b produced by pivoting of the pivot mechanism and the pivot center 13a of the pivot mechanism.
摘要翻译：意图是，可移动体的枢转所需的操作力可以保持基本上恒定，而与移动体的枢轴的角度位置无关。枢转机构（翻转机构10A）包括固定到期望位置的地板侧构件B，通过铰链联接而联接到地板侧构件B的座椅侧构件12，以便能够在预定角度范围内枢转以及扭转弹簧构件14，其配置成在与作用在座椅侧构件12上的重力相反的枢转方向上偏置座椅侧构件12。枢转机构被构造成使得绕作用在座椅侧构件12上的枢转中心13a的重力可以根据其枢转而改变。扭转弹簧构件14具有用于偏压座椅侧构件12的偏置部分14b和支撑在地板侧构件B上的支撑部分14a。支撑部分14b位于通过枢转机构和枢转机构的枢转中心13a的枢转产生的偏压部分14b。
