Abstract
The invention relates to a seat occupancy recognition device for recognising the occupancy of a seat, characterised by at least one volume detection device with at least one first sensor which is provided and designed to detect a volume on the vehicle seat, and at least one body function detection device with at least one second sensor, which is provided and designed to detect body functions, and at least one body function recognition device for recognising the detected body functions.
Claims14
A method for recognizing the seat occupancy of a seat,
- comprising:
- a. Performing a volume detection process for detecting a volume on a vehicle seat by a volume detection device, wherein the seat comprises the volume detection device,
- b. Performing a body function detection process by a body function detection device only after positive volume detection, wherein the seat comprises the body function detection device,
- c. Performing a body function recognition process by a body function recognition device only after positive body function detection, wherein the body function recognition process comprises at least one process of detecting a cardiac function and detecting a pulmonary function, wherein the seat comprises the body function recognition device,
- wherein after a negative body function recognition, either:
- (i) the body function detection process is performed again,
- (ii) one continues with method step a., or
- (iii) at least one additional body function is detected by the body function detection device.
5 more elements
A vehicle seat comprising:
- a seat occupancy recognition device for recognizing seat occupancy of a seat,
- having:
- at least one volume detection device having a first sensor, which is provided and designed for detecting a volume on the vehicle seat, and at least one body function detection device having a second sensor, which is provided and designed for detecting body functions, and at least one body function recognition device for recognizing the detected body functions, the volume detection device and the body function detection device being connected to a control device, the control device operating the body function detection device only in response to receiving signal from the volume detection device indicating that volume on the vehicle seat has been detected.
