JPH0632189A - Emergency roll bar - Google Patents

Abstract

PURPOSE:To provide a device for ensuring the safety of an occupant on a vehicle against danger such as the lateral turning and turn-over of a vehicle. CONSTITUTION:An extruding device, projecting a housed roll bar, is provided on struts 2. Usually, a projection preventive stopper 3 in a housed condition is fitted to the roll bar. A stopper releasing apparatus is provided on the stopper, and a circuit communicating between the apparatus and a danger sensitive sensor 4 is provided.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for protecting an upper portion of an occupant when a vehicle rolls over or overturns. 2. Description of the Related Art Conventional open-type or soft-top vehicles may be equipped with a roll bar or something similar thereto in case of danger such as rollover for safety. , In normal use, annoyingness or
Other than safety measures such as spoiling the appearance, it is in a bad condition. Therefore, each manufacturer increases the strength of the front pillar. Or, although the roll bar or something similar to it has been devised, the problem remains in terms of safety or openness. The present invention is an invention for solving such a problem. [0004] The structure will now be described. (A) A structure is provided in which the support portion of the roll bar can be projected and stored. (B) A structure for pushing out the roll bar will be provided on the column. (C) Normally, a stopper is provided to maintain the state where the roll bar support is stored. (D) A sensor that reacts in an emergency such as rollover or rollover, and a stopper release device are provided, and when the signal of the sensor is transmitted,
Provide a circuit that activates the stopper release device. (E) Provide a return prevention stopper to prevent the roll bar from protruding and being stored after it is formed. The apparatus is operated as described above. The operation of the present invention will be described. A danger detection sensor that performs an emergency detection reaction when a vehicle begins to roll over or overturn,
It detects it and sends a signal to the stopper release device to release the stopper. This causes the roll bar post extrusion structure to work to form the roll bar. At this time, the return prevention stopper operates at the same time to create a state in which the stopper is not stored.
In this way, the safety of passengers is ensured. [Embodiment] It should be noted that the purpose can be achieved even with two roll bar columns. Also, the strut extruded structure can serve the purpose of any conceivable structure. The stored roll bar can then be provided with a switch that can actuate this device to form the roll bar, depending on the occupant's will, which allows for more versatility. Further, it is possible to provide a releasing device capable of storing the roll bar when the danger sensor is activated to form the roll bar in an emergency or when an emergency does not occur. [0007] Therefore, it is possible to sufficiently secure safety against an accident without damaging the open feeling of a vehicle such as an open type or a soft top and a better appearance.

Claims (1)

(Claims) (a) A vehicle roll bar structure that is effective in an emergency. (B) Normally, the roll bar is stored inside the vehicle, and a danger detection sensor that reacts in an emergency such as when the roll bar begins to roll over or overturn is provided, thereby providing a device that causes the stored roll bar to protrude upward. (C) A structure that prevents the stored roll bar from returning to its original position after it has protruded, so that it will not be stored even if force is applied to the roll bar in an emergency.
