摘要： A rocking chair includes a seat, a backrest that is tiltable rearward, a locking spring portion that imparts resistance to the rearward tilting of the backrest, and a resilience adjustment member that changes the degree of resistance of the spring portion to the rearward tilting of the backrest. The resilience adjustment member is a cam that is rotationally operable by a person seated on a seat and the position in which rocking load due to the rearward tilting of the backrest is applied to the spring portion is changed by the cam, so that moment applied to the spring portion changes and the degree of resistance of the spring portion is adjusted.

摘要： A tilt mechanism is configured for adjustment of a tension applied by a chair back. The tilt mechanism includes a base, a back bracket tiltably supported on the base, and a rocker coupled to the back bracket so as to be moveable relative to the back bracket. The rocker has a pivot axis and pivots about the pivot axis when the back bracket tilts relative to the base. An energy storage mechanism is coupled to the rocker to exert a force onto a portion of the rocker. An actuating mechanism is coupled to at least one of the rocker or the energy storage mechanism and is configured to alter a distance between the pivot axis and the portion of the rocker at which the force is exerted onto the rocker, thereby altering a length of a lever arm.
摘要翻译：倾斜机构构造成用于调节由椅背施加的张力。倾斜机构包括基座，可倾斜地支撑在基座上的后支架和联接到后支架的摇杆，以相对于后托架可移动。当后支架相对于底座倾斜时，摇臂具有枢转轴线并围绕枢转轴线枢转。能量存储机构联接到摇杆上以对摇臂的一部分施加力。致动机构联接到摇臂或能量存储机构中的至少一个，并且被配置为改变枢转轴线和摇臂的施加在摇臂上的部分之间的距离，从而改变杠杆臂。

摘要： A chair includes a seat, a back rest, a frame having a curved rail, and a runner moveable along the rail. The seat and back rest are carried by the runner such that the seat and back rest can be moved together along the rail, and the position of the back rest relative to the seat changes in a horizontal direction as the seat and the back rest move along the rail. Additionally, the height-adjustable seat can be folded.

摘要： Reaction force mechanism for backrest of a chair has clear large space under the seat and uses a longer reaction force spring than the prior art. The mechanism includes a base member supported on a leg, a back support member coupled by a rotation shaft to the base member to recline and support the backrest, a seat support member to which the seat is mounted, a weight-dependent reaction force mechanism for moving the seat support member in a lifting direction, and a reaction force spring for applying a spring force for returning the back support member to an original position, in which the reaction force spring is disposed in a lateral orientation between the back support member and the seat support member.
