Device for detecting vibrating signal caused by tire engaging safety insert after pressure loss in tire
First Claim
1. A device for detecting the bearing of a tire of a vehicle, equipped with a plurality of tire, rim and safety insert assemblies, the insert of each assembly being mounted between the rim and the radially inner face of the tire tread, on the corresponding safety insert, each assembly being capable of triggering the emission of a vibrating signal when the tire comes in contact with the insert after a pressure loss in the tire, comprising means of detection and treatment of said vibrating signal, including a single sensor capable of being mounted on the vehicle and sensitive to the signals emitted by each of the said assemblies, when the corresponding tire comes in contact with the respective insert, and an indicator capable of signaling to the occupant of the vehicle a run-flat condition in response to a signal picked up by said sensor.

5. A device for detection of bearing of a tire of a vehicle, equipped with a plurality of tire, rim and safety insert assemblies in which the safety inserts are mounted between the rim and the radially inner face of the tire tread, on the corresponding safety insert, each assembly being capable of transmitting a characteristic vibration to the chassis of the vehicle in response to the bearing of one of the tires on the corresponding safety insert as a result of a pressure loss in the tire, comprising:
-
means of detection and treatment of such predetermined characteristic mechanical vibration of the chassis of the vehicle; and
means of transmission of an alarm. - View Dependent Claims (6, 7, 8, 9)
