    • An inflatable seating pad (10) consists of a hand operated pump (12) integrated within the top surface to inflate the pad with air. The pad (10) has a shut-off connector (6) at one corner which locates and is connected to a pressure relief valve (8). In use, the pad (10) is inflated by pushing upon the hand operated pump (12) to over inflate the pad. The shut-off connector (6) maintains the pressure in the pad (10). To set the pressure to a desired pressure the user actuates the pressure relief valve (pre-set to optimum pressure) to operate the shut-off connector (6) to allow air to exhaust through the pressure relief valve.
    • 可充气座垫(10)由集成在顶表面内的手动泵(12)组成,以使空气充气。 垫(10)在一个角处具有切断连接器(6),其位于并连接到减压阀(8)。 在使用中,通过推动手动泵(12)使垫(10)膨胀以使垫膨胀。 切断连接器(6)保持垫(10)中的压力。 为了将压力设定到所需的压力,用户致动压力释放阀(预设为最佳压力)以操作截止连接器(6)以允许空气通过压力释放阀排出。
