Description

Device for FestguftYnkvson Personen-iri-a motor vehicle

with automatic accident unlocking and multi-point safety system The invention relates to a device for strapping people in one Motor vehicle with one attached to the belt, in one with the vehicle body connected belt buckle latching locking tongue, the belt buckle for Releasing the locking tongue has an unlocking device that is manual is operated via a button or via an automatic accident release. Farther the invention relates to a multipoint security system. Such, with a Restraint systems provided with belts have the task of securing the buckled or belted To hold the person firmly in the seat in the event of an accident so that the person is neither out of the Motor vehicle thrown out, nor otherwise injured. At least I should Such restraint systems reduce the risk of injury and the severity of the injuries mitigated and the death rate lowered, which is without a doubt when investing the belt is reached before starting the journey.

Wearing the belt is now legal in most countries prescribed and the failure to put on is threatened with a penalty or fine. Still there there are still a number of people who are reluctant or unwilling to use their seat belts. The reason for this is mainly to be seen in the fact that in the known restraint systems Buckled or belted people remain buckled even after the accident and, for example, in the event of an accident-related fire in the motor vehicle or the like - should the vehicle have landed on a deeper body of water - when sinking of the vehicle in the water no longer have the necessary time to close the seat belt buckle to solve. Added to this is the accident shock, which prevents considered action.

It is usually difficult for third parties to loosen the belt buckle, because they are often attached to overturned motor vehicles or jammed doors not come near. Now it is possible to cut the strap or straps, which can even be achieved with a single cut with a pair of specially designed scissors target. However, this assumes that the person wearing a seat belt is able to do the appropriate The cutting device can be handled properly in spite of the shock or injury caused by the accident. ses is included in the motor vehicle. If there is no cutting device, there are also third parties barely able to sever the straps.

The object of the invention is therefore to provide the restraint device to improve the type specified in the preamble of claim 1 that the unlocking tongue is automatically released after the accident-related impact and the locking tongue of the belt is released. Another object of the invention consists in further improving the safety of the existing restraint systems and in particular to ensure that the seat belt is actually used before starting the journey is created. Furthermore, the theft protection of the motor vehicle should also be there increase. In addition, the accident detection by third parties should be improved and self-rescue in borderline accident situations can be increased. By remote-controlled unlocking The seat belt buckles will continue to make it easier to take off the seat belt, and thus achieved an increase in comfort. The device should be simple in structure and be designed to save space, as it should also be possible, the device for automatic unlocking afterwards with existing restraint devices to be installed and retrofitted.

To solve this problem are in the characterizing the invention Part of claim 1 specified features provided, with still in the further Claims for the task solution advantageous and beneficial advanced training claimed will.

In the restraint device according to the invention is therefore in the buckle a cable or Bowden cable attached to the unlocking device is arranged, activated by a time-delayed current pulse after the accident-related impact Electric gear motor is withdrawn, so that this the unlocking device spends in the release position in which the locking tongue is released. At a certain negative acceleration generated by the impact speaks a trigger mechanism and closes the circuit with a time delay between the electric motor and the vehicle battery or the secondary battery, so that the motor is set in motion and so the Bowden cables via a hook-in, or transfer device attracts, whereby the unlocking educational facility is shifted into the unlocked position.

The trigger mechanism also activates the hazard warning lights. The window motor is activated in parallel with the electric motor, i.e. the pull motor opens that or the window panes.

So that the person using the motor vehicle is forced to use the belt Before starting the journey, a limit switch or the like is still in the seatbelt buckle. arranged that the circuit for the engine ignition, or the starter motor closes when the locking tongue is engaged. Furthermore, an additional Switch be provided, which is arranged in a hidden place in the motor vehicle that is known only to the person authorized to use the vehicle. on this effectively prevents theft of the vehicle. To start the Motor vehicle even if the electrical circuit required for the invention fails To ensure a switch is provided through which the system for the invention bridged and thus the motor vehicle can start.

This particular switching state is via a glow lamp or the like. displayed.

The arrangement of the cable Bowden cable or the like. The normal Function of the belt buckle is not hindered in any way.

The user can thus use the unlocking device after completion unlock while driving as usual by pressing the unlocking button. The automatic only takes action in the event of an accident. It comes to one. Accident, that's how it will be Seat belt released after the accident so that the seat belt was still in place during the accident Person can get out of the vehicle without difficulty or be pulled out by helpers without the awkward and often impossible cutting of the belt is required. Furthermore, the automatic lowering of the window panes an emergency exit for the user, as well as a better option for emergency rescue workers created. This is in the case of jammed or locked door locks due to an accident particularly effective. In addition, the hazard warning lights should be switched on automatically and the accident warning horn to indicate the accident quickly for quick help to ensure. The accident warning horn should continue to serve the purpose of the casualty through the emergency signal möolihst et c ohn 1 1 these facilities will ueh Valuable time saved, which benefits the casualty. Furthermore, through a shut-off system prevents the seat belt buckles from unlocking automatically, if, for example, due to an accident-related roof position of the motor vehicle, a subsequent Injury to vehicle occupants by opening the seat belts cannot be ruled out can be.

For example, to put older passengers down and get out of the car Easing out of the motor vehicle is easy one for the motor vehicle driver achievable remote release of the unlocking devices provided. To a control The security and automatic unlocking system must continue to be guaranteed a control button is provided. A second battery (), e.g. in the passenger compartment, remains even if the on-board power supply is destroyed, e.g. in the event of a frontal collision, the power supply for the safety devices mentioned in the invention guaranteed.

The invention will now be explained in conjunction with the aid of exemplary embodiments explained in more detail with the drawing. The figures show: FIG. 1 a lateral schematic View of the seat belt buckle.

Figure 2: The train electric motor with translation and tensioning device.

Figure 3: The technical connection of the electrical components.

The representation shown in Figure 1 consists essentially of the actual belt buckle (1), which is indicated by the dashed housing (2) encapsulated to the outside and via the retaining strip (3) on the motor vehicle body is attached. The locking tongue (4) is engaged in the belt buckle (1) to which the belt is attached. The belt device is therefore in the locked position shown, in which the locking tongue (4) is held in the belt buckle (1) and the seat belt is on the person wearing the seat belt. To unlock is the unlocking device (5) arranged with the unlocking button (6). Will if the unlocking button (6) is pressed in the direction of arrow A, the unlocking device (5) the locking tongue (4) released and pushed out of the belt buckle (1). As can now be seen from FIG is shown on a T.eL of the unlocking device (5) a Bowden cable (7) attached through a socket. (8) from the housing (2) is led out, and is provided with an insulation (9). At the same time recognizes a limit switch (10) in the buckle (1) which is arranged so that it is at not engaged locking tongue (4) the ignition or starter circuit of the Motor vehicle interrupts. When the locking tongue (4) is engaged the circuit is closed. This limit switch thus forces the motor vehicle user for putting on the belt and thus increases safety.

As can be seen in Figure 2, is on the shaft () of the electric motor (12) a disc (13) with a circular appearance. On this disc (13) is a Pull rod (11), which at the other end with a swivel flap (14), which the clamping device (15) includes attached. A limit switch (16) is attached next to the disc. If a negative acceleration is now generated by an accident-related impact, the electric motor (12) is excited by the accident voltage pulse via a time delay (17), connected to voltage. Thus it begins to turn from position B in direction of the arrow B, thereby the swivel flap (14) over the pull rod (11) in the direction of the arrow C moves, at the same time this is fixed in the clamping device (15) Bowden cable (7) pulled in the direction of arrow C.

In this way, as can be seen in FIG. 1, the unlocking device (5) attached Bowden cable (7) moves in the direction of arrow C. In this way the unlocking device (5) is then pivoted in the direction of arrow E. and the belt buckle (1) ejected in the direction of arrow F. This leads to the electric motor (12) when it reaches position D through the seat belt buckle located limit switch (10) is disconnected from the circuit, but is parallel to it the circuit through the limit switch (16) on the electric gear motor (12) can be seen in Figure 2 and 3, closed again. If position B is thus reached, the remains The engine stops again as its circuit is interrupted again.

The illustration shown in Figure 3 includes the electrical system the invention. It can be seen that in the belt castle (1) the located chatr UÖ, 'only after putting on the seat belt, i.e. after The locking tongue (4) engages, the circuit closes and thus a relay (18) 18 'attracts; thus the contacts (18 ") are closed. When the anti-theft switch (19) is switched on, you can operate the starter (20) as soon as the locking tongue (4) is in the belt buckle (1). Due to a negative acceleration caused by an accident, i.e. in the event of an accident, an automatic system (21) is activated through which over a relay (22) the hazard warning lights (23) switched on and a pulse at the same time on a time delay (17) is given. The time lag can be considered more fixed Value must be entered, this value being selected in such a way that activation of the Electric motor (12) via a relay (24) and the closing of the contact (24 ') The vehicle in the accident comes to a standstill. Here the relay 4) is activated by means of Time delay (17) applied voltage, its contact (24 ') is closed. Of the Electric traction motor (12) begins to turn; except when the car is involved in an accident Assumes roof position, because then this current path would be through an emergency shutdown system (25) unlocked. When the vehicle is in the normal position, the motor (12) rotates until Ejection of the belt tongue, whereby the relay (18) drops out and the contacts (18 ') ( be opened; the motor stops, but is activated again by a limit switch (16) connected to voltage until it has reached its starting position (B), the limit switch (16) is open again, but the time delay can also depend on the negative acceleration forces be controlled.

Such that the start of activation is set at the point in time in which the acceleration forces drop to the value zero, or the motor vehicle has come to a standstill.

At the same time you can see that a Accident warning horn (26) is switched on and after the accident process via a button 01) can be switched off.

It can also be seen that at the same time as the electric train motor (12) Power window motor (27) is applied and the window or windows opens and is switched off via a limit switch (28).

In addition, you can see a switch (29) that controls the electrical System of the invention bridged to the starter even in the event of a failure of this system WO) to be able to operate.

This switching state is particularly indicated by a control lamp 00) marked.

An emergency shutdown 25) of the automatic unlocking can also be seen. This is sometimes necessary in borderline situations if an accident has occurred Loosening the belt poses a risk or injury to the vehicle user cannot be ruled out, i.e. if the vehicle is in an accident-related position on the roof.

In addition, one recognizes in Figure 3 a control button (32) to the check entire systems. You can also see a button (34) with a remote unlocking device (33) to make it easier to take off the seat belt.

From Figure 3 you can also see a battery 05), the one Secondary battery in a suitable place in the motor vehicle or the normal motor vehicle battery can be.

Finally it should be pointed out that the entire invention can also be retrofitted to existing restraint devices without difficulty, as well as other changes, i.e. e.g. improvement and minimization of the system, of the invention are possible that are within the scope of the inventive concept. Simultaneous Component changes or other design of the components, as well as digitization within the meaning of the invention, are claimed as the inventor's claim.
