摘要： An electrical system includes a movable component configured for selective connection with and selective removal from a mounting surface. The movable component may include a first electronic control unit (ECU), and an electromechanical interface configured for selectively locking the movable component with said mounting surface. The electrical system may include a second ECU configured to communicate with the first ECU, and/or a third ECU configured to detect a potential dynamic event via one or more sensors. The third ECU may be configured to provide dynamic event information to the second ECU. The second ECU may be configured to provide disable information corresponding to the dynamic event information to the movable component. The first ECU may be configured to lock the movable component with the mounting surface according to the disable information.

摘要： A circuit arrangement to control at least one valve includes at least one actuator with at least one positioning element adjustable between at least one first position and a second position. At least one driver unit activates the actuator and a control unit operates the driver unit. At least one air mass measuring device measures an air mass flowing through the valve. The control unit processes an output signal of the air mass measuring device. Valves, valve arrangements, seat comfort systems, and methods all use such circuit arrangements.

摘要： To provide a seat adjustment device capable of flexibly changing a shape of a seat. A seat adjustment device for adjusting a shape of a seat includes a pad including an elastomer, and airbags disposed on a front surface and a rear surface of the pad. The airbags are adjustable in amount of air therein. The airbags include a first airbag disposed on one of the front and rear surfaces and of the pad, and a second airbag disposed on the other. The first airbag is longer than the second airbag in a direction substantially perpendicular to the front and rear surfaces of the pad. The second airbag is longer than the first airbag in a direction substantially parallel to the front and rear surfaces of the pad.

摘要： A gradual adjustment system and method of a lumbar support of a seat enables a protruding portion on a surface of a chair back to slide to improve comfort of the seat. The system comprises an air bag grouping the chair back corresponding to a waist position of a human body. The air bag group consists of at least three partially overlapping air bags arranged from top to bottom. The air level of each air bag is adjusted by a control module operating an air distributing valve. The control module comprises a plurality of adjusting buttons capable of controlling other adjacent air bags to correspondingly exhaust air when one air bag is inflated, and is connected to, via a signal, a timing unit capable of recording an air filling time or an air emptying time of each air bag in the air bag group controlled by any one of said adjusting button, thus enabling the protruding portion of the lumbar support to slide linearly, and differing from a conventional method of controlling air filling and emptying a single air bag.
