Definitions
- the invention relates to an arrangement for fastening a gas generator, in particular a tubular gas generator, in a housing, in particular in a diffuser of an airbag module.
- a gas generator in particular a tubular gas generator
- a diffuser which has an opening for introducing the gas generator.
- the diffuser surrounds the gas generator on all sides and has a larger diameter than this (EP-A-0 631 908 AI).
- the gas generator it is also known to connect the gas generator to the diffuser at its end faces. Because of the larger diameter of the diffuser, it is provided at its opening with an adapter that compensates for the differences in diameter between the diffuser and the gas generator. After inserting it into the diffuser, it lies against the adapter and is screwed to the diffuser on the opposite side in such a way that it is clamped against the adapter.
- sheet steel parts are used as adapters.
- the disadvantage of sheet steel parts is that they are expensive and heavy and that they can only be mounted on the diffuser by means of a device. This has a negative impact on the production process and causes additional assembly costs.
- the invention has for its object to enable the assembly of a gas generator, in particular tubular gas generator in a housing, in particular in a diffuser using an adapter more cost-effectively and without adversely affecting the production process.
- the adapter is made of plastic according to the invention and the housing lies at least at one point next to the adapter and / or in the region of an opening of the adapter directly on the gas generator in the effective direction of the fastening screw.
- the housing preferably has at least one web which runs through the adapter or next to the adapter and abuts an end face of the gas generator.
- This arrangement has the advantage that the gas generator is clamped directly to the housing when it is screwed on.
- the plastic adapter is located between the housing and the gas generator and is only axially loaded with a small force. As a result of this reduced load, a setting behavior of the plastic adapter is excluded. The sealing effect is retained even when exposed to heat.
- the plastic adapter is cheaper and lighter than a sheet metal version. Another advantage is that it is attached to the diffuser by hand can be, which results in advantages in terms of assembly time. Additional devices can be omitted.
- the web preferably lies against an end face of a generator flange and it is furthermore expedient that two webs are provided.
- Figure 1 is a side view of a diffuser.
- FIG. 3 shows a plan view of a plastic adapter
- Fig. 4 shows a longitudinal section through a diffuser with a gas generator arranged therein.
- a diffuser 1 for a tubular gas generator 2 (FIG. 4) has an open end 3 for the insertion of the tubular gas generator 2. At the other end of the diffuser, an opening 4 is provided for a bolt 5 of the tubular gas generator. By means of the bolt 5, one end of the tubular gas generator is connected to the diffuser by means of a nut 6.
- the latter has two webs 7, 8. Furthermore, there is a plastic adapter 9, which is provided with two openings 10, 11 for receiving the webs 7, 8.
- the adapter has an outer contour in plan view, the course of which essentially corresponds to the outer contour of the diffuser.
- the adapter has a groove 12 for receiving in the area of its outer contour the front edge 13 of the diffuser. This groove 12 runs almost over the entire circumference, and runs out in a shoulder 14 in the lower region of the diffuser.
- the top view of the adapter has an inner contour which essentially corresponds to the outer diameter of the tubular gas generator 2. This is provided in the region of the adapter with a flange 15 which has an outer diameter such that it can rest on the adapter with an end face 16.
- the tubular gas generator is now assembled in such a way that the plastic adapter 9 is first plugged onto the diffuser 1, the webs 7, 8 extending into the openings 10, 11.
- the length of the webs and the thickness of the adapter are coordinated so that the ends of the webs are still a small amount, e.g. by a few hundredths of a millimeter, within the plastic adapter.
- the tubular gas generator is then pushed into the diffuser, the bolt 5 being guided through the opening 4.
- the tubular gas generator is connected to the diffuser.
- the end face 16 of the flange 15 bears against the plastic adapter.
- the plastic adapter is slightly deformed by further tightening, so that a sealing effect occurs between the plastic adapter and the diffuser or the flange 15.
- the webs 7, 8 now directly touch the end face 16 of the flange 15.
- the flange 15 and thus the tubular gas generator are braced directly relative to the diffuser 1, while the plastic adapter does not deform any further .
- the diffuser 1 is fastened in the motor vehicle by means of bolts 17.
