[0035] In this embodiment, multiple sensing units 1 can be independently installed at different positions on the vehicle seat to detect the pressure on different parts of the passenger. Compared with the prior art, each sensing unit 1 is connected to the control unit 5 separately, is independently designed, is easy to arrange, and will not affect the pressure detection function of other parts after partial damage, thus improving the service life of the sensing system.

[0036] In this embodiment, the pressure acquisition device 3 is electrically connected between the flexible pressure sensor 2 and the control unit 5. After the flexible pressure sensor 2 detects the passenger's pressure, it transmits the pressure signal to the pressure acquisition device 3, which then converts the pressure signal into an electrical signal and transmits it to the control unit 5.

[0037] In this embodiment, electrical connection refers to the connection between pressure acquisition device 3 and control unit 5. Pressure acquisition device 3 can collect pressure signals collected by flexible pressure sensor 2 and convert the collected pressure signals into electrical signals.

There are at least two back flexible pressure sensors, and all back flexible pressure sensors are electrically connected to the back pressure acquisition device 9. The back pressure acquisition device 9 is electrically connected to the main cable 4.

[0046] The backrest 21 has at least two flexible back pressure sensors, including an upper flexible back pressure sensor 7 and a lower flexible back pressure sensor 8. The upper flexible back pressure sensor 7 is arranged on the upper part of the backrest 21 to detect the pressure on the upper side of the passenger's back, and the lower flexible back pressure sensor 8 is arranged on the lower part of the backrest 21 to detect the pressure on the lower side of the passenger's back.

Both the upper back flexible pressure sensor 7 and the lower back flexible pressure sensor 8 are connected to the back pressure acquisition device 9, which is connected to the main cable 4.

[0048] When a passenger sits in the vehicle seat, the upper part of the passenger's back rests against the upper side of the backrest 21.

The first side wing flexible pressure sensor 11 is recessed towards the inside of the backrest 21 to detect pressure on one side of the passenger's waist. The second side wing flexible pressure sensor 13 is recessed towards the inside of the backrest 21 to detect pressure on the other side of the passenger's waist.

[0056] In this embodiment, the first side wing flexible pressure sensor 11 is installed on one side of the backrest 21 in the width direction, directly opposite the passenger's waist. The first side wing flexible pressure sensor 11 is connected to the main cable 4 through the first side wing pressure collector 12 (one of the side wing pressure collectors 15).

[0057] When a passenger sits in the vehicle seat, one side of the passenger's waist rests against one side of the backrest 21 in the width direction. The first side wing flexible pressure sensor 11 detects the pressure of the passenger's waist against the backrest 21. The pressure signal detected by the first side wing flexible pressure sensor 11 is transmitted to the first side wing pressure collector 12, which converts the pressure signal into an electrical signal and transmits it to the main cable 4, which then transmits it to the control unit 5.

The second side wing flexible pressure sensor 13 detects the pressure of the other side of the passenger's waist against the backrest 21. The pressure signal detected by the second side wing flexible pressure sensor 13 is transmitted to the second side wing pressure collector 14, which converts the pressure signal into an electrical signal and transmits it to the main cable 4, which then transmits it to the control unit 5.

[0060] In this embodiment, both the first side wing flexible pressure sensor 11 and the second side wing flexible pressure sensor 13 are arc-shaped. The first side wing flexible pressure sensor 11 and the second side wing flexible pressure sensor 13 are located on both sides of the width direction of the backrest 21, and are arranged opposite to each other. The first side wing flexible pressure sensor 11 is recessed towards the inside of the backrest 21 of the vehicle seat, and the second side wing flexible pressure sensor 13 is recessed towards the inside of the backrest 21 of the vehicle seat. That is, the first side wing flexible pressure sensor 11 arches towards the direction close to the passenger's waist, and the second side wing flexible pressure sensor 13 arches towards the direction close to the passenger's waist. This can fill the bend of the passenger's waist and conform to the curve of the passenger's waist, so as to more accurately detect the pressure of the passenger's waist on the backrest 21.

[0070] When a passenger sits in the vehicle seat, their legs rest on the seat cushion 22, and the upper part of their back leans against the upper side of the backrest 21. The upper back flexible pressure sensor 7 detects the pressure of the upper part of the passenger's back against the backrest 21, and the pressure signal detected by the upper back flexible pressure sensor 7 is transmitted to the back pressure collector 9, which then transmits the signal to the main cable 4. The lower part of the passenger's back leans against the lower side of the backrest 21, and the lower back flexible pressure sensor 8 detects the pressure of the lower part of the passenger's back against the backrest 21. The pressure signal detected by the lower back flexible pressure sensor 8 is transmitted to the back pressure collector 9, which then transmits the signal to the main cable 4. The first side wing flexible pressure sensor 11 detects the pressure of one side of the passenger's waist against the backrest 21. The pressure signals detected by the first side wing flexible pressure sensor 11 are transmitted to the first side wing pressure collector 12, which converts the pressure signals into electrical signals and transmits them to the main cable 4. The second side wing flexible pressure sensor 13 detects the pressure of the passenger's waist on the other side of the backrest 21. The pressure signals detected by the second side wing flexible pressure sensor 13 are transmitted to the second side wing pressure collector 14, which converts the pressure signals into electrical signals and transmits them to the main cable 4. The pressure signals detected by the two leg flexible pressure sensors 17 are transmitted to the leg pressure collector 18, which converts the pressure signals into electrical signals and transmits them to the main cable 4. The main cable 4 transmits the electrical signals from each pressure collector 3 to the control unit 5.
