Particularly, the contriver finds, existing seat 300 with motorized adjustment function, and generally between 50mm-60mm, generally about 240mm, the range of regulation at backrest 320 inclination angles is generally at 50 °-70 ° for the amplitude that front and back are regulated for the amplitude of its up-down adjustment.The contriver finds, when being sitting on the seat 300, seat 300 actual present positions all do not reach up and down chaufeur (or be sitting on the passenger side passenger) or the inclination angle of front and back end position and backrest 320 also reaches far away the inclination maximum position.
The contriver is undertaken finding after a large amount of research by the seat 300 to different driving ages and different automobile types, the actual position of general seat 300 all has above the stroke more than the 50mm from rear end position, in height with the smallest limit position stroke above 30mm is arranged, backrest 320 has at least with inclination maximum backward and surpasses 30 ° stroke, in other words, usually, actual position for seat 300, has the stroke of 50mm at least with rear end position, and has the stroke of 30mm at least with the smallest limit position, backrest 320 has 30 ° of strokes at least with the angular limit position that retreats simultaneously, in view of this, when vehicle generation head-on crash or Frontal offset impact, can take full advantage of these limit travels, for example control seat 300 integral body mobile backward, and move down, control simultaneously backrest 320 certain angle that recedes, thereby increase seat 300 front space.
That is, when vehicle generation head-on crash or Frontal offset impact, controller control seat 300 integral body backward, move down and control backrest 320 and recede, can greatly increase seat 300 front space thus, improve vehicle security.
Shown in seeing figures.1.and.2, when Fig. 1 is vehicles failed generation head-on crash or Frontal offset impact, seat 300 and dummy's 400 position, when Fig. 2 is vehicle generation head-on crash or Frontal offset impact, seat 300 and dummy's 400 position, comparison diagram 1 and Fig. 2 can find after bumping, since seat 400 backward, move down and backrest 310 recedes, thereby effectively increased front space.Wherein, Fig. 3 is the operating principle sketch of seat 300 when collision happens, the cushion after wherein 310 ' expression is moved, the backrest after 320 ' the expression action.But, should be appreciated that Fig. 1, Fig. 2 and Fig. 3 only are for the purpose of signal, can not be interpreted as it is the actual position of seat 300 after collision happens.
Thus, can when crashing, can automatically adjust by front-row seats 300 according to the vehicle of the embodiment of the invention, to realize promoting the purpose of occupant's activity space, reduce the injury that the occupant is subject to, the safety that has improved vehicle.
According to one embodiment of present invention, vehicle body comprises A post 200, and sensor is located in the A post 200.Further, sensor is located at the top of A post 200.
Because head-on crash or Frontal offset impact when occuring in vehicle, A post 200 very easily is out of shape, thereby inwardly compress the space of operator seat or co-driver, therefore by sensor being located in the A post 200, and preferably be located at the top of A post 200, thus more responsive to the collision of vehicle, when collision happens, sensor can send collision alarm to controller rapidly, thereby transmits control signal to be driven seat 300 actions by corresponding motor by controller.
Certainly, the present invention is not limited to this, and in an alternative embodiment of the invention, vehicle body comprises front windshield, and sensor is located at the upper end of front windshield.Thus, sensor can send collision alarm to controller equally rapidly when vehicle generation head-on crash or Frontal offset impact.
Because the contriver finds the actual position of general automatic seat 300 and has the distance of 50mm apart from rear end position at least, therefore when vehicle generation head-on crash or Frontal offset impact, consider that seat 300 is mobile to discharge front space fully backward, avoid simultaneously the too backward mobile rear row passenger that wounds of seat 300, the contriver finds by a large amount of tests, seat 300 backward during mobile 15mm-25mm effect better, and be preferably 20mm.
Therefore, according to some embodiments of the present invention, when controller receives the collision alarm that sensor sends, motor-driven seat 300 integral body mobile 15mm-25mm backward before and after the controller control.Further, when controller received described collision alarm, controller control front and back motor-driven seat 300 is mobile 20mm backward.
Equally, the contriver finds that the actual position of general automatic seat 300 has the distance of 30mm at least apart from the smallest limit position, therefore when vehicle generation head-on crash or Frontal offset impact, consider that seat 300 fully moves down to discharge head room, the contriver finds by a large amount of tests, the distance that seat 300 integral body move down effect when 20mm-30mm is better, and is preferably 25mm.
Therefore, according to some embodiments of the present invention, when controller received the collision alarm that sensor sends, controller control lifting motor drove seat 300 integral body and moves down 20-30mm.Further, when controller received described collision alarm, controller control lifting motor drove seat 300 and moves down 25mm.
Based on same reason, the contriver finds that the actual position of the backrest 320 of general automatic seat 300 has 30 ° stroke at least apart from the angular limit position that retreats, therefore when vehicle generation head-on crash or Frontal offset impact, consider that backrest 320 fully recedes to discharge front portion and head room, avoid simultaneously backrest 320 too to recede wounding rear row passenger, the contriver finds by a large amount of tests, it is better that backrest 320 rolls oblique angle effect in the time of 1 °-10 ° backward, and be preferably 5 °.
Therefore, preferably, according to preferred embodiments more of the present invention, when controller received the collision alarm that sensor sends, controller control Angle Modulation Motor drove the backrest recliner so that backrest 320 recedes 1 °-10 °.Further, when controller received described collision alarm, controller control Angle Modulation Motor drove the backrest recliner so that backrest 320 recedes 5 °.
To sum up, when having an accident, when especially 200 distortion of A post are serious, with A post 200 associated components (such as top cover) will certainly be to internal modification, the extruding inner space, seat 300, secondary instrument desk and car door may limit the occupant and can not carry out actv. and dodge simultaneously, and this moment, occupant's head and chest may be subject to larger injury.Therefore; vehicle is when bumping according to an embodiment of the invention; by control seat 300 integral body backward, move down certain distance; controlling simultaneously backrest 320 rotates to an angle backward; thereby can increase a part of activity space to the occupant; reduce to a great extent the probability that the occupant comes to harm, the occupant safety that adequately protects improves the car load crash survivability.
