    • A diaphragm pump for a seat adjusting device comprises an enclosure (11) and at least one diaphragm (23, 24) disposed within the enclosure (11) to delimit a first pump chamber (21) and a second pump chamber (22). Each one of the first and second pump chambers (21, 22) respectively has a gas inlet (15, 17) and a gas outlet (16, 18). The at least one diaphragm (23, 24) includes at least one dielectric elastomer film (23, 24). At least a portion of the dielectric elastomer film (23, 24) is sandwiched between electrodes (25-27) to form a dielectric elastomer actuator. The at least one diaphragm (23, 24) is attached to the enclosure (11) such that the at least one diaphragm (23, 24) is displaced relative to the enclosure (11) when a voltage applied to the electrodes (25-27) is altered, such that a volume of one of the first and second pump chambers (21, 22) is increased and a volume of the other one of the first and second pump chambers (21, 22) is decreased by the displacement of the at least one diaphragm (23, 24).
    • 用于座椅调节装置的隔膜泵包括外壳(11)和设置在外壳(11)内的限定第一泵室(21)和第二泵室(22)的至少一个隔膜(23,24)。 第一和第二泵室(21,22)中的每一个分别具有气体入口(15,17)和气体出口(16,18)。 所述至少一个隔膜(23,24)包括至少一个介电弹性体膜(23,24)。 介电弹性体膜(23,24)的至少一部分夹在电极(25-27)之间以形成电介质弹性体致动器。 当施加到电极(25-27)上的电压时,至少一个隔膜(23,24)附接到外壳(11),使得至少一个隔膜(23,24)相对于外壳(11) )被改变,使得第一和第二泵室(21,22)中的一个的体积增加,并且第一和第二泵室(21,22)中的另一个的体积由于 至少一个隔膜(23,24)。
