Description

The present invention relates to a belt trainer, for example for training in a simulator for the driver's seat position in a motor vehicle in the context of simulating an accident sequence and rescuing (internal or external rescue) from the motor vehicle.

Various tools are known for cutting through security goods, in particular for rescuing (own or external rescue) from a car.

So reveals the DE 31 17 916 A1 For example, a tool for cutting security goods from which DE 30 42 025 A1 a knife for cutting a seat belt and a mandrel for smashing a car window are known and the DE 40 41 401 A1 teaches a pair of scissors for cutting open a seat belt and a spike for breaking a car window.

All technical solutions for cutting through safety goods are used to rescue people after traffic accidents, whereby the entire seat belt arrangement becomes unusable when the belt is cut, so that the entire seat belt arrangement must be replaced when the vehicle is repaired after the accident.
The disadvantage here is that none of the technical teaching provides a means for practicing / training in an emergency after a traffic accident.

Driving simulators for cars for training or test purposes of driving a vehicle are known per se in a wide variety of embodiments, most of which are used to simulate unstable or unsafe driving conditions in motor vehicles.

DE 44 02 129 A1 discloses, for example, a device for moving and positioning any body in space around any axis and in defined, previously determinable positions for simulating movements and accelerations, in particular in the form of flight or driving simulators.

DE 100 34 731 A1 discloses a motion drive for simulating the rolling motion of a car in order to simulate the driver's physical feeling for centrifugal acceleration when cornering.

DE 199 11 050 A1 discloses a device for simulating driving operation of a motor vehicle under rainy conditions in order to simulate driving in the rain by sprinkling water on the vehicle that is actually moving.

DE 101 13 501 A1 discloses a method for simulating a side impact of a vehicle using a computer simulation.

DE 10 2005 042 259 A1 discloses a sled system for simulating a side crash of a vehicle, with which an associated realistic penetration kinematics of a vehicle side part into the vehicle interior for testing the effect of the restraint systems, the seat stability and the side protection devices can be simulated at different side impact points, impact angles and impact speeds over the entire side of the vehicle.

DE 10 2006 044 086 A1 discloses a driving simulator for the virtual simulation of traffic situations, in particular accident-critical dangerous situations.

WO 2016/134389 A1 discloses a driving simulator with a display in the form of a projection surface of a projector.

WO 2016/110488 A1 discloses a driving simulator for training braking behavior.

The disadvantage of these known driving simulators is that while accident-critical dangerous situations are represented, there is no seat belt trainer, e.g. for training in a simulator for the driver's seat position in a motor vehicle as part of the simulation of an accident sequence and the subsequent rescue (self-rescue or external rescue) from the Motor vehicle, is taught.

The invention is therefore based on the object of specifying a belt trainer for motor vehicle seat belts, inter alia in combination with a simulator for training an accident and rescue procedure from the motor vehicle, with multiple training of cutting the seat belt being possible without having to do this after each Cutting process the entire seat belt assembly must be replaced.

According to the invention, this object is achieved by the features of claim 1. Further favorable design options of the invention are specified in the subordinate claims.

The belt trainer comprises a belt strap and a flexible carrier, the dimensions of which correspond to the average dimensions of the area covering the human chest and stomach area (ie length in the range from approx. 20 to 70 cm and width from 15 to 40 cm) Area is preferably rectangular (with or without rounded corners), and the thickness is about 2 to 10 mm and with the webbing long opposite the surface of the carrier (and can be rolled up as a roll at its second free end).
The surface of the carrier can, however, also have a different geometric shape [for example. trapezoidal shape (with or without rounded corners) or oval shape].
The belt strap is a disused or a new seat belt.

The length of the carrier, based on the average adult male person, is preferably approximately 50 cm and the width approximately 30 cm. For women, the length and the width of the wearer are smaller than the wearer for men, according to the known size ratios.

In at least two diagonally opposite areas near the corners of the carrier, the carrier is provided with elongated recesses passing through the material of the carrier, which are referred to as loop openings, at least two of these loop openings being arranged parallel to one another, the distance between them three loop openings is approximately twice the width of the individual loop opening.
However, it is also within the scope of this invention that only one loop opening is provided in the areas near the corners of the carrier, three loop openings in the areas near the corners of the carrier being particularly advantageous.
These loop openings are used to receive the belt by threading it through the loop openings.

The width of the loop opening corresponds to the thickness a of the belt used, the length of the loop openings being equal to the width b of the belt (so that the belt can be pulled through the loop openings and is locked / fixed in the tightened state through the three loop openings). This locked / fixed state is similar to the real state of the seat belt in the tightened state, with the tightening of the belt in the direction of the original belt lock on the belt trainer by pulling (by hand) on the first free end of the belt (downwards towards the stomach and feet of the user Person). In the case of a simulator of the sitting position, a belt buckle can also be provided for receiving the seat belt.

Due to the clamping effect (locked / fixed state) of the belt in the loop openings of the wearer, in addition to the cut training option, the belt can also be tightened quickly after the cut and, if necessary, the belt can be quickly replaced with another belt, which means a very high number of training sessions is ensured.

The carrier can also be provided with such a loop opening in the areas near its four corners, with the strap always running through the loop opening in the areas of the diagonally opposite corners.

The carrier can advantageously be provided with a through-hole which is located between two of its corners, near the carrier outer edge. This hole is used for better handling of the carrier when it is used as intended.

The material of the carrier is advantageously stable, but flexible plastic, so that the belt does not deform or destroy the loop opening when the belt is tightened, the carrier being designed in the form of a plate.

When used as intended, a belt container can be positioned in front of the chest and stomach area of a person with a tightened belt in order to be able to cut the belt in the area of the sternum. At the same time, the belt container protects against unwanted injuries in the chest and stomach area when cutting.
To this end, the surface of the carrier can also be provided with the graphic representation of the corresponding bones of the relevant skeletal area of the person (chest-stomach area) for clear positioning.

However, it is also within the scope of the invention that a belt container is positioned behind the back, opposite the chest and stomach area of a person with a taut belt, directly above the chest and stomach area. This is for more experienced people as there is no direct protection between the belt cutting tool

It is also possible for two straps to be positioned in front of and behind the person in the chest and abdomen, with the belt in the upper shoulder area through the loop opening of both straps (first through the three loop openings of the wearer behind the person's back and then is passed through the three loop openings of the wearer in front of the abdomen and chest of the person).

With the belt trainer, a seat belt can be severed multiple times for exercise purposes without the entire seat belt arrangement having to be replaced after each severing process.

The person can stand freely in the room, sit on a piece of furniture, a seat in any vehicle or on the seat in a simulator of the driver's seat position.

The belt trainer is used for the realistic severing of original belt material for the purpose of repeated training of cutting techniques, the comparison / selection of different tools for cutting the seat belt and the recognition / avoidance of dangers as well as the risks of rescuing yourself and others after a traffic accident, e.g. under realistic conditions of a vehicle simulator for training an accident and rescue process, because the incorrect use of rescue tools, such as a belt cutter, to cut through belt material and / or their incorrect use mean not only ineffectiveness, but also mean additional risk of injury for rescuers and the accident victim.

With the belt trainer it is possible to bring belt material (old or new material) into the original belt position in seconds (with or without a simulator of the sitting position in a motor vehicle) and thus to achieve an efficient and cost-effective training and test option.

The simulator of the seating position has all the essential elements in the vicinity of the driver's seat for safety training on a motor vehicle, ensuring good accessibility and visibility of the driver's position from the outside and the simulator being transportable at the same time.

The simulator comprises a base body, at least one seat, at least one operating element and a steering element, the base body being provided with four transport rollers or wheels which carry the base body and the base body has a frame with a driver-side contour between the A and B -Pillar that is self-supporting.

The simulator can be provided with additional modules, such as an airbag or window module, in order to display the consequences of accidents in the passenger compartment of the simulator with little effort.

The in 2 The belt trainer shown includes a belt strap ( 4th ) and a flexible carrier ( 1 ), whose dimensions correspond to the average dimensions of the human area covering the chest and abdominal area. That means the length of the surface of the beam ( 1 ) is in the range of approx. 20 to 70 cm and the width of the surface of the carrier ( 1 ) is in the range of 15 to 40 cm, whereby the area is preferably rectangular and the corners ( 2 ) of the carrier ( 1 ) can also be rounded.

Preferably the length of the beam is ( 1 ), based on the average adult male person about 50 cm and the width about 30 cm. For women, the length and the width of the wearer are smaller than the wearer for men, according to the known size ratios.

The area of the beam ( 1 ) can also have a different geometric shape (for example trapezoidal or oval).

The thickness of the beam ( 1 ) is around 2 to 10 mm.

The length of the webbing ( 4th ) advantageously corresponds to a multiple of the length of the area of the beam ( 1 ), where the webbing ( 4th ) at its second free end ( 42 ) can be rolled up.

The webbing ( 4th ) is a disused or a new seat belt without any fittings or accessories.

In at least two diagonally opposite areas near the corners ( 2 ) of the carrier ( 1 ) is this with elongated, due to the material of the carrier ( 1 ) through recesses ( 3 ) provided as loop openings ( 3 ), with three of these loop openings ( 3 ) are arranged parallel to each other, the distance between these three loop openings ( 3 ) approximately twice the width of the individual loop opening ( 3 ) is. These loop openings ( 3 ) are used to take up the webbing ( 4th ) by passing it through the loop openings ( 3 ) is threaded through.

However, it is also within the scope of the invention that only one loop opening ( 3 ) (not shown in the figures) or two loop openings ( 3 ) (not shown in the figures) in the areas near the corners ( 2 ) of the carrier ( 1 ) is provided, with three loop openings ( 3 ) in the areas near the corners ( 3 ) of the carrier ( 1 ) are particularly advantageous. It is also conceivable that more than three loop openings ( 3 ) are available, whereby the increase in the number makes the manageability of threading and retightening the webbing ( 4th ) is made more difficult.

The width of the loop opening ( 3 ) corresponds to the thickness ( a ) of the webbing used ( 4th ), where the length of the loop openings ( 3 ) the width ( b ) of the webbing ( 4th ) so that the webbing ( 4th ) through the loop openings ( 3 ) can be pulled and through the three loop openings ( 3 ) is locked / fixed in the tightened state. This locked / fixed state is similar to the real state of the seat belt in the tightened state, whereby the tightening of the belt strap ( 4th ) in the direction of the original belt lock on the belt trainer by pulling (by hand) on the first free end ( 41 ) of the belt (down towards the abdomen and feet of the user).

Due to the clamping effect (locked / fixed state) of the belt strap ( 4th ) in the loop openings ( 3 ) of the carrier ( 1 ) In addition to the cutting training option, you can also quickly tighten the belt strap ( 4th ) after the cut and, if necessary, a quick replacement of the belt strap ( 4th ) by another strap ( 4th ) possible, which ensures a very high number of training sessions.

The carrier ( 1 ), as in 1 shown in the areas near its four corners ( 2 ) with such a loop opening ( 3 ), whereby the loop opening ( 3 ) in the areas of the diagonally opposite corners ( 2 ) with the webbing ( 4th ) are crossed (see 2 and 3 ).

Advantageously, the carrier ( 1 ) with a through hole ( 5 ), which is located between two of its corners ( 2 ) near the outer edge of the beam. This hole ( 5 ) serves for better handling of the carrier ( 1 ) with its intended use.

The material of the carrier ( 1 ) is advantageously more stable but flexible plastic so that the belt strap ( 4th ) the loop openings ( 3 ) not deformed or destroyed when the belt is tightened, whereby the carrier ( 1 ) is plate-shaped.

When used as intended, a belt container, as in 4th shown in front of the chest and abdomen of a person with the belt strap tightened ( 4th ) positioned around the webbing ( 4th ) to be able to cut in the area of the sternum. At the same time, the belt container protects against unwanted injuries in the chest and stomach area when cutting.
The surface of the carrier ( 1 ) to be provided with the pictorial representation of the corresponding boils of the relevant skeletal area of the person for clear positioning (not shown in the figures).

However, it is also within the scope of the invention that a belt container, as in 5 shown, behind the back, opposite the chest and abdomen of a person with the belt strap tightened ( 4th ) is positioned directly over the chest and abdomen. This is for more experienced people as there is no direct protection between the belt cutting tool and the body.

It is also possible that two carriers ( 1 ), as in 6th shown, positioned in front of and behind the person in the chest and abdomen, the belt in the upper shoulder area through the loop opening of both straps (first through the three loop openings of the wearer behind the back of the person and then through the three loop openings of the wearer in front of the person's abdomen and chest).

A seat belt can be cut several times with the belt trainer Exercise purposes possible without having to replace the entire seat belt assembly after each cutting process. The belt trainer, as in 7th can be used for demonstration purposes without a human person by positioning it in a stand (or leaning against a wall, which is not shown).

When the belt trainer is used as intended, the person can stand freely in the room, sit on a piece of furniture or on the seat in a simulator of the driver's seat position.

The in 8th simulator shown in external view ( 8th ) the seating position, which can have a belt trainer, has all the essential elements in the vicinity of the driver's seat for safety training on a motor vehicle, ensuring good accessibility and visibility of the driver's position from the outside, with the simulator being transportable.
