Definitions
- the invention relates to a method for operating an occupant restraint device for protecting an occupant on a vehicle seat in an automated vehicle, wherein the occupant restraint device has at least one airbag and a seat belt with at least one belt tensioner as restraint elements and a control unit of the occupant restraint device distinguishes at least between an upright position and a reclining position of a seat back of the vehicle seat.
- the control device has at least one sensor element for determining the position of the vehicle seat, so that the control device distinguishes in a restraint situation between a first situation in which the vehicle seat with the vehicle occupant is in a position in the region of a standard position relative to the gas bag of the first restraint element, and a second situation in which the vehicle seat with the vehicle occupant is in a position outside the standard position.
- a method for operating an occupant restraint device for protecting an occupant on a vehicle seat, in particular a belt-integrated seat, in an automated vehicle, wherein the occupant restraint device has at least one airbag and a seat belt with at least one belt tensioner as restraint elements, is also distinguished by means of a control unit of the occupant restraint device at least between an upright position and a reclining position of a seat back of the vehicle seat.
- a belt status of at least occupants of a front row of seats of the vehicle in the longitudinal direction of the vehicle is recorded.
- the procedure can largely meet all legal and so-called rating requirements with relative certainty.
- the vehicle seat having the reclining position does not require any additional adaptation to the occupant restraint device in order to apply the method, so that it can be used both for the upright position of the seat back and for the reclining position of the seat back and the occupant.
- a seat structure of the vehicle seat and its connection to a floor assembly of the vehicle must fundamentally meet the strength requirements for the belt integral seat, so that no additional effort is required to carry out the procedure.
- a seat belt tensioner is activated and the seat belt is tightened in the shoulder belt area by an electric motor.
- a lap belt tensioner and a seat-integrated retractor tensioner are also activated and pyrotechnically activated.
- Another embodiment provides that at the time of activation of the pyrotechnic belt tensioning, an upright positioning of the vehicle seat backrest is pyrotechnically released by releasing a lock on the seat backrest.
- the aim here is a force-controlled straightening of the occupant, driven by an impact energy at the time of the collision.
- the impact usually straightens the seat backrest without any further force being applied, whereby the method provides for the controlled straightening of the seat backrest. Due to the straightening of the seat backrest, comparatively serious injuries to the occupant's lumbar spine can be largely avoided.
- the vehicle seat particularly the seat backrest
- relatively high forces will act on the occupant's spine in the event of a collision, and will be absorbed by the seat surface in particular due to compression caused by the occupant's pelvis being supported by the seat.
- This compression of the spine can be largely prevented by uprighting the seat backrest.
- the upright positioning of the seat back is braked before the seat back reaches an upright end position, so that the load acting on the occupant due to the upright positioning and an undamped abrupt braking of the seat back and the associated risk of injury, in particular to the occupant's cervical spine, can be reduced.
- Another possible embodiment of the method provides that while the seat back is in the upright position until it reaches its upright end position, the electromotive belt tensioning of the shoulder belt area and a lap belt area of the seat belt is maintained at a predetermined force level. The occupant is therefore still tied to the vehicle seat, with the lap belt area being tightened at a maximum force level in order to essentially prevent the occupant from slipping under the lap belt area of the seat belt. This slipping or diving through is also known as the submarining effect.
- a starting point for an internal deceleration caused by the longitudinal movement of the vehicle seat can be selected such that an initial moderate vehicle deceleration initially takes place without the internal deceleration and the longitudinal movement of the vehicle seat is released by the pyrotechnic release of the lock as soon as a maximum deceleration is applied to the vehicle. This maximum deceleration is reached when the vehicle is no longer moving during the collision.
- the vehicle seat is braked in a damped manner in the area of its longitudinal end position in the direction of travel. In other words, the vehicle seat is braked in a damped manner at the end of an inner deceleration path.
- the longitudinal movement of the vehicle seat is therefore not stopped abruptly, so that a load resulting from an abrupt stopping of the longitudinal movement of the vehicle seat does not act on the occupant, which means that an additional risk of injury to the occupant can be largely excluded.
- one embodiment provides that when the longitudinal end position of the vehicle seat is reached, the force level of the electromotive tightening of the seat belt in the shoulder belt area is reduced by a predetermined amount.
- the shoulder belt force i.e. the force level of the tightening of a belt force limiter
- the occupant in particular his upper body, is allowed to move forward in order to reduce residual body energy, in particular acceleration energy. The movement therefore ends in the vehicle seat. It is possible to specify a force level to which the tightening force of the seat belt in the shoulder belt area is reduced, depending on the weight of the occupant on the vehicle seat.
- a respective knee airbag is deployed in a first stage in order to This provides additional impact protection for the occupant on the vehicle seat against the relatively hard contours of the vehicle interior. This further reduces the risk of injury to the occupant.
- Fig. 1 schematically shows a section of a vehicle with an occupant on a vehicle seat in an upright position
- Fig. 3 shows a schematic section of the vehicle with the occupant in the lying position in the event of a detected imminent collision with the vehicle
- Fig. 4 shows a schematic section of the vehicle with the occupant on the vehicle seat in the lying position after the collision has occurred
- Fig. 6 schematically shows a section of the vehicle after the seat back of the occupant’s vehicle seat has been raised
- Fig. 7 shows a schematic section of the vehicle during a longitudinal movement of the vehicle seat in the direction of travel
- Fig. 8 shows a schematic section of the vehicle with the occupant on the vehicle seat and the driver airbag and knee airbag deployed.
- Figure 1 shows a section of a vehicle 1 with an occupant 2 on a vehicle seat 3 with an upright seat back 3.1, so that the occupant 2 has an upright sitting position on the vehicle seat 3.
- this sitting position of the occupant 2 can be referred to as the driving position.
- Figure 2 shows a section of the vehicle 1 with the occupant 2 on the vehicle seat 3 in a lying position.
- Figures 3 to 8 each show a section of the vehicle 1 with the occupant 2 on his vehicle seat 3 before and during a collision, in particular a frontal collision.
- an occupant restraint device comprising restraint elements R1 to Rn, a comparatively high level of injury protection for the occupant 2 on the vehicle seat 3 can be achieved provided the vehicle seat 3 is in an upright position and the occupant 2 on the vehicle seat 3 is in an upright sitting position.
- variable seating positions in particular a reclining position of the occupant 2 on the vehicle seat 3, the seat back 3.1 of which is correspondingly inclined, a functioning and thus a protective effect of the restraint elements R1 to Rn of the occupant restraint device shown in more detail in the following figures is limited.
- the restraint elements R1 to Rn cannot or only inadequately fulfil their protective function for the occupant 2, so that despite activated or triggered
- the vehicle 1 has an assistance system for automated, in particular autonomous ferry operation, in which a driving task is carried out entirely by the vehicle 1, in particular by the assistance system.
- the following describes a method for operating an occupant restraint device of the vehicle 1, which optimizes protection against injury for the occupant 2 in the reclining position of the vehicle seat 3 and thus a protective function for the reclining occupant 2 can be ensured as far as possible.
- the method enables a comparatively safe kinematic restraint for a driver and a front passenger as occupants 2 from the reclining position in the event of a collision of the vehicle 1, in particular a frontal collision.
- the vehicle seat 3 is an integral belt seat in which the safety belt 4 with its components is arranged on the vehicle seat 3 or is integrated into it.
- a connection of the vehicle seat 3 to a main floor of the vehicle 1 is designed in terms of its strength to meet the requirements for load cases in relation to the vehicle seat 3.
- the occupant restraint device of the vehicle 1 has the seat belt 4 with an electromotive retractor R1, a pyrotechnic retractor (not shown in detail), an electromotive pelvic retractor R2, a two-stage triggerable driver airbag R3, a two-stage triggerable passenger airbag (not shown in detail), a telescopic and/or deformable steering column R4, a seat slide R5 with a pyrotechnic triggerable movement mechanism, the seat back 3.1 as a so-called kinematic back R6 with a pyrotechnic triggerable kinematic mechanism and a knee airbag R7.
- Figure 3 shows a section of the vehicle 1 with the occupant 2 in the lying position in the event of a detected impending collision with the vehicle 1, in particular a frontal collision.
- the fastened seat belt 4 is tightened by an electric motor by means of the activated A ufro II tensioner R1, whereby the occupant 2 is fixed to the vehicle seat 3, in particular to the seat back 3.1.
- the activation of the roller tensioner R1 takes place as a function of detected signals from an environmental sensor system of the vehicle 1, for example based on detected signals from at least one radar-based sensor.
- a ufro II tightener R1 is pyrotechnically triggered and the electromotive pelvic tightener R2 is activated. This tightens the seat belt 4 at all three end points, as shown in Figure 4.
- a movement of the seat back 3.1 i.e. the kinematic back R6, is pyrotechnically released.
- the release takes place by means of an airbag unit, for example an airbag control unit.
- a locking mechanism which for example comprises two locking bolts, is pyrotechnically released so that the occupant 2 is raised upright by means of the kinematic back R6, i.e. has an upright sitting position.
- the aim is therefore to force-controlledly prop up occupant 2, driven by the impact energy resulting from the collision.
- the seat back 3.1 Due to the collision, i.e. the impact, the seat back 3.1 straightens up without any further force being applied.
- An upright positioning is controlled, whereby the upright positioning of the seat back 3.1 is braked before the seat back 3.1 reaches an upright end position.
- a dampened braking of the seat back 3.1 takes place by means of at least one end position damper (not specified in more detail). Such end position damping when the seat back 3.1 reaches the upright end position reduces a peak load acting on the occupant 2.
- Consumables for controlling the force of the upright positioning of the seat back 3.1 can be produced by known technologies, for example by cutting, wire drawing, etc. directly on the recliner, i.e. on vehicle seat 3.
- the end position damping can also be implemented in this way.
- a belt force acting on the occupant 2 by means of the safety belt 4 is greater than a force for upright positioning of the seat back 3.1, wherein the belt force can be very large due to a switchability in relation to a force level.
- the occupant 2 is fixed to a seat cushion 3.2 of the vehicle seat 3 forming a seat surface with the maximum force level of the pelvic tensioner R2 in order to prevent slipping under a lap belt area of the safety belt 4, as shown in Figure 6.
- a tensioning force acting on a shoulder belt area of the safety belt 4 also remains comparatively high until the upright end position of the seat back 3.1 is reached.
- a controlled longitudinal movement of the vehicle seat 3 in the direction of travel of the vehicle 1 is pyrotechnically released, as shown in Figure 7.
- a lock of the vehicle seat 3 in particular a lock of the seat slide R5 by means of bolts in relation to seat rails, is pyrotechnically released.
- the longitudinal movement of the vehicle seat 3 with the occupant 2 is referred to as internal deceleration, since this takes place inside the vehicle 1.
- the occupant 2 with the vehicle seat 3 initially only decelerates with a certain force level below a force level of a belt force limiter and is braked uniformly within the vehicle 1.
- the occupant 2 has a lower deceleration due to a forward movement, whereby peak loads acting on the occupant 2 can be avoided as far as possible.
- a starting time of the internal deceleration can be selected, whereby an initial moderate vehicle deceleration initially takes place without internal deceleration.
- the internal deceleration i.e. the release of the vehicle seat 3 to execute the Longitudinal movement occurs when vehicle 1 has its maximum deceleration.
- the maximum deceleration of vehicle 1 is reached when vehicle 1 is no longer moving during the collision, i.e. the accident.
- An approximately rectangular characteristic curve can be modulated due to a uniform deceleration.
- the force level can be adjusted depending on the weight of the occupant 2, so that a certain forward displacement path can be made available to the occupant 2 at the end of his movement.
- the driver airbag R3 and the knee airbag R7 are also triggered in a first stage.
- the driver airbag R3 triggered in the first stage when the steering column R4 is retracted and the steering wheel 5 of the vehicle 1 is in the retracted position, impact and/or collision with relatively hard contours of a vehicle interior is largely prevented. Additional impact and/or collision protection is therefore ensured, whereby a relatively soft cushioning of the head and chest of the occupant 2 can be ensured.
- a seat occupancy detection system determines that a passenger seat of vehicle 1 is occupied alternatively or additionally, a passenger airbag is triggered in a first stage.
- the knee airbag R7 which is triggered in the first stage, also ensures additional impact protection for the occupant 2 on the vehicle seat 3 against comparatively hard contours of the vehicle interior, with the kinematics of the occupant 2 being supported by the knee airbag R7. The risk of injury for the occupant 2 can thus be reduced even further.
- the driver airbag R3 and the knee airbag R7 they have a lower degree of inflation and are therefore less hard when impacted by occupant 2.
