Abstract
An electric reclining chair has a base, a linkage mechanism, a leg rest mount, and a control module. The linkage mechanism is movably mounted to the base and connected to a driver. The leg rest mount is pivotally connected to the linkage mechanism. The control module has a sensor module and a control unit. When the linkage mechanism and the leg rest mount are being folded by the driver, if an object is under the leg rest mount and abuts the leg rest mount, the leg rest mount pivots relative to the linkage mechanism, which is sensed by the sensor module. Thus, the control module controls the driver to stop folding the linkage mechanism or to unfold the linkage mechanism so as to prevent the object from being pinched.
Claims17
An electric reclining chair with anti-pinch protection comprising:
- a base;
- a linkage mechanism movably mounted on the base and connected to a driver;
- at least one leg rest mount pivotally connected to the linkage mechanism;
- and
- a control module having
- at least one sensor module;
- and
- a control unit electrically connected to the at least one sensor module and the driver for controlling the driver to unfold or fold the linkage mechanism;
- wherein if the at least one leg rest mount pivots relative to the linkage mechanism when the linkage mechanism is being folded, the at least one sensor module senses pivoting of said leg rest mount relative to the linkage mechanism to send a signal to the control unit such that the control unit controls the driver to stop folding the linkage mechanism or to unfold the linkage mechanism.
