A seat for a vehicle may include a seatback including an intermediate portion including a first portion having a first stiffness and including a second portion including a second material different from the first material of the first portion, the seat back quickly couples the associated occupant and dissipates as much energy as possible. The intermediate portion may be configured such that when at least a portion of the back of the seat occupant is urged against the front face of the seat back and the seat back is at least partially compressed, a reaction force from the seat back against the at least a portion of the back of the occupant increases from a minimum reaction force to a first reaction force corresponding to the first displacement, and thereafter further displacing as the front face of the seat back displaces, the reaction force is reduced to a second reaction force.
一种用于车辆的座椅可包括座椅靠背,所述座椅靠背包括中间部分,所述中间部分包括具有第一刚度的第一部分以及包括第二部分,所述第二部分包含与第一部分的第一材料不同的第二材料,使得座椅靠背迅速耦接相关联乘员和消散尽可能多的能量。中间部分可配置成使得在座椅乘员的后背的至少一部分推压抵靠座椅靠背的正面并且座椅靠背被至少部分地压缩时,来自座椅靠背抵抗乘员后背的至少一部分的反作用力从最小反作用力增加到与第一位移对应的第一反作用力,并且之后随着座椅靠背的正面的位移进一步移位,所述反作用力减少到第二反作用力。
