Definitions
- the invention relates to an airbag for a side impact protection device according to claim 1.
- the gas bag which is still filled, can represent a hindrance in rescuing an occupant.
- the present invention has for its object to provide an airbag for a side impact protection device, in which the airbag is filled protectively over a longer period of time, but which does not represent an obstacle to an occupant rescue.
- the gas bag according to the invention for a side impact protection device is characterized in that, in addition to a protective chamber which serves to catch a vehicle occupant, there is an additional chamber in which an outflow opening is provided.
- the protective chamber and overflow chamber are connected to one another via an overflow line.
- the gas bag according to the invention has the advantage that the outflow of the gas in the gas bag is delayed by the arrangement according to the invention.
- the gas is first led into the protective chambers, which gives the gas bag its protective effect.
- the gas then flows via the overflow line into the overflow chamber, where it leaves the gas bag via the outflow opening.
- the gas flows out of the protective chamber faster or slower.
- the time in which the gas bag is filled in a functional manner can be set very easily via the outflow speed of the gas.
- an airbag for a side impact protection device can thus be made available which is filled with protection for a longer period, for example for the period of a vehicle rollover, and at the same time is vented again for occupant rescue.
- the gas bag can consist of a coated or laminated fabric.
- a coated or laminated fabric has the advantage that the gas in the gas bag cannot escape through the fabric. This supports that the gas bag remains filled with protection over a longer period of time.
- Gas generators can be used to fill the gas bag, the gas of which cools only slightly when relaxing. The fact that the gas initially maintains its temperature ensures that the pressure in the gas bag is as constant as possible over a longer period of time.
- the gas bag according to the invention has several overflow chambers. These can be arranged in positions apart from one another in the gas bag, so that a uniform outflow is ensured in all areas of the gas bag.
- overflow lines can lead to an overflow chamber. If these overflow lines are connected to different protective chamber areas, this arrangement also supports a uniform outflow of the gas located in the gas bag. This ensures that the gas bag for occupant rescue is vented again.
- the outflow speed can also be adjusted by coordinating the size of the overflow line and the size of the outflow opening.
- a possible example of a ratio of the size of the cross section of the power line to the size of the outflow opening is 1: 1.
- Fig. 1 is a side view of an airbag according to the invention with two overflow chambers and
- Fig. 2 is a detailed view of the gas bag according to the invention shown in Fig. 1.
- the gas bag 1 shows an airbag 1 for a side impact protection device.
- the gas bag 1 is a so-called windowbag, which unfolds in front of the side windows in the event of a collision in a vehicle and thus represents an impact protector for the shoulder and head region for vehicle occupants.
- the gas bag 1 is characterized by different areas. Areas are provided, so-called protective chambers 2, which are filled with gas. On the other hand, the gas bag has areas 3 into which no gas can flow during filling.
- the protective chambers 2 are arranged where the likelihood of contact with a body part of a vehicle occupant is greatest.
- the gas bag 1 has overflow chambers 4 in addition to the protective chambers 2 and the non-filled areas 3.
- the overflow chamber 4 is connected to the protective chambers 2 via two overflow lines 5. It has an outflow opening 6.
- the overflow chamber 4 is arranged in the unfilled area 3. This unfilled area 3 can either be sewn or woven.
