  • Patent number: 5197560
    Abstract: A hood safety stop mechanism for restricting backward movement of a hood, which is bendable convexly upward relative to the car body during a front-end collision of a vehicle, includes an elongated opening formed in either the hood or the car body, and a hook, secured to the other of the hood and car body. The hook is formed so as to be located within the opening without any engagement with an edge of the opening. During a collision, the hook is initially brought into engagement with the edge of the opening when the hood begins to open and after the hood has opened to a predetermined engaging angle. The hook is then disengaged from the opening when the hood begins to bend during further opening of the hood. Finally, the hood is fully bent to a predetermined bend angle.
