可调节的活动靠背座椅
Abstract:
本发明的一方面涉及一种升降活动靠背座椅，所述升降活动靠背座椅包括底座部分(12)、枢转地连接到底座部分的座位部分(14)、枢转地连接到座位部分的靠背部分(16)、第一致动器(62)和第二致动器(64)，上述第一致动器用于相对于底座部分移动座位部分，而上述第二致动器用于相对于座位部分移动靠背部分，以便改变座椅的构型。在所有座椅构型中，致动器都基本上封闭在一对对置结构的底座部分侧板(18)之间的座椅底座部分内。座位部分枢转地连接到侧板(18)上，并可在底座部分内回缩和套装位置到升起位置之间活动，其中座位部分从底座中伸缩地伸出。套装的构型可以减少在座椅活动部分之间的夹住的危险。
Abstract(English):

One aspect of the invention concerns a lift-recliner chair comprising a base portion (12), a seat portion (14) pivotally connected to the base portion, a back portion (16) pivotally connected to the seat portion and a first actuator (62) for moving the seat portion with respect to the base portion and a second actuator (64) for moving the back portion with respect to the seat portion so as to alter the configuration of the chair. The actuators are substantially enclosed within the base portion of the chair between a pair of opposed structural base portion side panels (18) in all configurationsof the chair. The seat portion is pivotally connected to the side panels (18) and is movable between a retracted and nested position within the base portion to an raised position in which it is telescopically extended from the base. The nested configuration can reduce the risk of entrapment between moving parts of the chair.
