International ClassesB60R 21/02 (20060101)B60R 21/08 (20060101) AbstractA safety device for a vehicle that uses inertia to prevent the upper body of an occupant from colliding with the windshield. A pair of bars are slidingly held to the underside of the vehicle's roof. The bars each have a row of gear teeth in engagement with a semi-circular gear. A net is secured to the semi-circular gears so that as inertia causes the sliding bars to move forward the gears turn and introduce the net between the occupants and the windshield. A ratchet wheel assembly prevents the safety device from moving backwards unless the pawls are manually released. | |
