  • Patent number: 4823059
    Abstract: A control for a motorized deck lid pull down mechanism which does not require the use of mechanically activated limit switches for detecting deck lid positions or the presence of closing or sealing obstructions. Detection of specified pull down conditions as well as the presence of deck lid obstructions is achieved by monitoring the magnitude of motor current in relation to various predefined motor current thresholds. Engagement of the deck lid with obstructions during the pull down sequence will cause the motor current to exceed the closing and sealing thresholds, terminating or reversing the respective function.

  • Patent number: 4707027
    Abstract: A pneumatically cushioned vehicle seat and apparatus and method to adjust the same is provided by the present invention. A novel switching and pumping arrangement for the pneumatic seat and/or seating combination allows the pump to inflate the pneumatic cushion and also deflate the pneumatic cushion. Use of the pump for deflation of the pneumatic cushion eliminates the need of the chair occupant pushing against the same cushion when adjusting the seat to a less firm position.
