ABSTRACT:
A safety vehicle (10) for passengers includes a horizontally disposed chassis (16) having a front (16a) and rear (16b) portion. The vehicle body (14) is disposed on the chassis (16) and includes a passenger section (20) disposed intermediate the front and rear portions of the chassis (16). The chassis (16) includes three lever arms (44, 46, 48) pivotally interconnected. The first lever arm (44) is disposed adjacent the front portion of the chassis (16). A second lever arm (48) is disposed adjacent the passenger section (20). The third lever arm (46) is pivotally interconnected to the first and second lever arms, such that the first end of the third lever arm is pivotally connected adjacent to the second end of the first lever arm (44) at a first pivot point (60). The second end of the third lever arm (46) is pivotally connected adjacent to the first end of the second lever arm (48) at a second pivot point (62). Upon impact, the chassis (16) front portion (16a) rotates about the first pivot point (60) in a first direction of rotation (68) and the chassis rear portion (16b) rotates about the second pivot point (62) in a second direction of rotation (70) opposite to the first direction of rotation (68) of the chassis front portion (16a) thereby removing the passenger section (20) from the linear impact forces created by the collision and translating a portion of the linear deceleration motion of the vehicle (10) into rotational motion of the passenger section (20).
