1. A backdoor system, the backdoor system comprising:
- a rear gate that defines an opening;
a backdoor that swings toward and away from the opening of the rear gate;
a cushioning device that is connected between the rear gate and the backdoor and cushions the backdoor relative to the rear gate; and
a gate-side pressure sensor that is placed on the rear gate at a location next to the cushioning device to detect both of;
a pinched object that is pinched between the rear gate and the cushioning device; and
a pinched object that is pinched between the rear gate and the backdoor;
a backdoor-side pressure sensor that is placed on a peripheral location of the backdoor to detect the pinched object that is pinched between the rear gate and the backdoor, whereinwhen the backdoor is positioned to fully close the opening of the rear gate, the gate-side pressure sensor is opposed to the backdoor-side pressure sensor and is spaced apart from the backdoor-side pressure sensor,when the backdoor is positioned to fully close the opening of the rear gate, the backdoor-side pressure sensor, the gate-side pressure sensor and the cushioning device are arranged in this order from outside the rear gate toward a center of the opening in a direction perpendicular to a swing direction of the backdoor, andthe cushioning device is a gas damper.

Abstract
A pinched object detection apparatus includes a couple of pressure sensors arranged at lateral end portions of a backdoor of a vehicle and another couple of pressure sensors arranged at lateral end portions of a rear opening of the vehicle. An object pinched between the lateral end portions of the rear gate and the backdoor can be detected with the corresponding pressure sensor arranged at the backdoor or pressure sensor arranged at the rear opening. Furthermore, an object pinched between the lateral end of the rear opening and an opposing gas damper can be detected with the corresponding pressure sensor arranged at the rear opening.
