A manually actuated inflation device for upholstered parts on motor vehicle seats, for example lumbar vertebra column supports, consists of a rubber ball in which an outlet valve is arranged at one end of the ball and is actuated via an actuation knob. Inside the rubber ball, an outlet line and two non-return valves are provided which feed air into the upholstered bodies to be inflated when the rubber ball is pressed together by hand and permit air to be sucked in when the rubber ball is released. The entire arrangement is very compact and, arranged on one side of the vehicle seat, can be easily actuated with one hand. |
