Definitions
- the present disclosure relates to a method for occupant protection, an occupant protection system, and a motor vehicle with such an occupant protection system.
- the existing side airbag restraint systems are developed for specific sitting positions and postures, the size and mounting position of airbags are fixed, which cannot adapt to the increasingly diversified sitting postures arising with the development of intelligent vehicles.
- the current side curtain airbags cannot cover the area below the lower edge of the car window, and as a result, after the occupant adjusts the inclination of the seat by a large angle, the protective effect of curtain airbags will be greatly reduced or the curtain airbags cannot provide any effective protection; in addition, when the occupant lies down, the change of his/her sitting position will cause the protection of seat-side airbags to displace away from the critical body parts of the occupant that are vulnerable to injuries.
- the half-lying posture is more common in the co-driver’s seat but is less common in the driver’s seat, since the driver needs to drive and operate.
- the hands and feet of drivers will be gradually freed, so a restraint system that is applicable to both traditional and future sitting postures becomes necessary. Therefore, a new challenge is posed for occupant protection to adapt to different sitting postures.
- a method for occupant protection of a motor vehicle comprising the following steps:
- S1 acquiring body characteristic information of an occupant and seat position information
- This provides the advantage that an optimal airbag position for occupant protection can be obtained via adjustments made based on the body type characteristics of the occupant and the current position and state of the vehicle seat, such as an upright sitting posture, a lying-down or half-lying position of the co-driver’s seat, or a lying-down or half-lying position of the driver’s seat during automated driving.
- the method further comprises:
- the body characteristic information includes height, weight, body size, gender and/or age of the occupant.
- the seat position information includes the position, the height of a cushion and/or the inclination of a backrest of a vehicle seat.
- the method further comprises:
- an occupant protection system for a motor vehicle for implementing the method according to the first aspect of the disclosure, wherein the occupant protection system at least comprises:
- the sensor system is configured to be suitable for detecting the body characteristic information of an occupant and/or the seat position information
- the actuator is configured to be suitable for moving the position of each of the airbags
- analysis and control unit configured to be suitable for calculating the optimal protective position for each of the airbags based on the body characteristic information and/or the seat position information, such that the actuator is controlled to adjust the position of each of the airbags to the optimal protective position.
- the airbag is a side airbag.
- the component of the motor vehicle is a vehicle seat.
- the sensor system comprises:
- the body characteristic sensor is configured to be suitable for detecting height, body size, gender, age, position and/or posture of the occupant

- the seat pressure sensors are arranged at various parts of the vehicle seat, and wherein the seat pressure sensors are configured to be suitable for detecting pressures on each part of the vehicle seat.
- the body characteristic sensor is configured to be suitable for running face recognition on the occupant.
- the analysis and control unit is able to determine a sitting posture of the occupant according to the detected position, the height of the cushion, the inclination of the backrest and/or the pressure of the vehicle seat.
- the actuator comprises a sliding rail and a slider arranged on the sliding rail, wherein the airbag is fixedly connected to the slider, and wherein the airbag is able to be driven to move along the sliding rail via the slider.
- the occupant protection system comprises an input device, wherein the body characteristic information can be manually input into the analysis and control unit through the input device.
- the occupant protection system comprises an indication device, wherein the indication device is configured to be suitable for indicating the current position of each of the airbags in a visual, auditory and/or tactile manner, wherein the indication device particularly comprises a vehicle dashboard, a loudspeaker and/or a vibration feedback device.
- a motor vehicle comprising the occupant protection system according to the second aspect of the disclosure for implementing the method for occupant protection of a motor vehicle according to the first aspect of the disclosure.
- the position of the side airbag restraint system can be dynamically adjusted according to different body sizes of the occupants and the positions of the seats, thereby achieving an optimal occupant protection strategy.
- FIG. 1 schematically shows a schematic view of an interior of a motor vehicle 100 according to the disclosure, wherein airbags 11, 12, 13 are shown in a triggered state.
