    • The invention relates to alternating pressure pads for use as mattresses or cushions and, in particular, provides an improved cover for the inflatable cells forming the pressure pad. In one aspect, the cover has a top cover sheet and a depending side flap portion, the inflatable cells being attached to the flap portion by attachment means, either directly or via an upstanding wall portion of a base sheet, the top cover sheet having a portion which masks the attachment means. The invention also includes a quick release connector for an air supply to an inflatable mattress, which comprises releasably engageable male and female connector parts, the female part having a socket terminating in an end wall bounding the entrance to the socket; the male part including a projection to be received in the socket, a handle linked to a cam, the handle being pivotably mounted on the outside of the male part adjacent to the end wall when the parts are engaged, the handle being arranged so that pivotal movement of the handle biases the cam part against the end wall of the projection in the socket and permits separation of the connector parts.
    • 本发明涉及用作床垫或垫子的交替压力垫,并且特别地,为形成压力垫的可膨胀单元提供改进的盖。 在一个方面,盖具有顶盖片和悬垂侧翼片部分,所述可充气细胞通过附接装置直接或经由基片的直立壁部附接到翼片部分,顶盖片具有 遮蔽附着装置的部分。 本发明还包括用于向充气床垫供气的快速释放连接器,其包括可释放地接合的公和母连接器部件,所述阴部件具有端接在限定所述插座入口的端壁中的插座; 所述阳部件包括待接收在所述插座中的突起,连接到凸轮的手柄,当所述部件接合时,所述手柄可枢转地安装在所述阳部件的与所述端壁相邻的外侧上,所述手柄被布置成枢转 手柄的运动将凸轮部分偏压在插座中的突起的端壁上并允许连接器部分的分离。
