Document Type and Number:
Japanese Patent JPS59195424
Kind Code:
A
Abstract:
A device for monitoring the operation of pneumatic seats for vehicles, the seats being supported by a pneumatically-operated spring to give a resilient seat mounting. The monitoring device operates at the commencement of use of the seat and also during use of the seat in case of possible leaks of air. Sensing elements are located at positions above and below a rated central position and are actuated according to movements of the seat from the centralposition. Actuation the sensing elements provides signals for a counter device which when an upper or lower limiting value is reached automatically resets itself to a starting value between the two limiting values and emits a control signal corresponding to the limiting value reached. The control signal operates an air valve for a predetermined length of time to supply air to or discharge air from the pneumatic spring.
