Definitions
- the invention relates to a knee air bag module of a vehicle occupant restraint system.
- Knee airbag modules serve to protect the knee and shin region of a vehicle occupant and are disposed in a lower portion of an instrument panel or in the footwell adjacent to the instrument panel.
- the gas bag of the knee gas bag module is hidden until its unfolding behind the dashboard or behind a footwell cover.
- the airbag enters the vehicle interior and unfolds along the instrument panel in the direction of the vehicle occupant.
- the knee airbag module is mounted on the underside of the instrument panel above the footwell, and upon deployment, the airbag must first be moved downwardly out of the housing and then upward in an occupant-directed direction
- This arrangement and deployment sequence distinguishes these "low-mounted” modules from the so-called “mid-mounted” modules, which are arranged in the central area of the instrument panel and have an opening directed towards the occupant, through which the gas bag extends substantially in the horizontal direction exit, then unfold before the shins or knees of the inmate.
- the object of the invention is to improve the exit and deployment behavior of the gas bag in the activation of the "low-mounted" knee gas bag module.
- This object is achieved with a knee airbag module of a vehicle occupant restraint system, which has an outer housing in which a gas bag folded together before its deployment into a gas bag package and a gas generator are accommodated, which generates filling gas for filling the gas bag.
- an outlet opening oriented downward in the installed position is formed, through which the gas bag leaves the outer housing during deployment.
- the gas bag is subdivided into a plurality of serially arranged fluidically communicating chambers, wherein the gas generator next chamber is separated from an adjacent chamber by a wall which extends in the inflated airbag substantially in the region of the outlet opening and along the outlet opening.
- the gas generator next chamber is arranged in the installed position above the adjacent chamber.
- the gas generator next chamber is already filled directly after the activation of the knee gas bag module, wherein the inflow of the filling gas and the filling of the gas generator next chamber advantageously forms the first inflation step after the activation of the knee gas bag module.
- the outlet opening can be released by opening a flap that conceals it prior to the activation of the knee-airbag module downwards and in the direction of the vehicle interior.
- the remaining, still folded airbag package when filling the gasgenerator next chamber can be moved as a compact unit from the outer housing through the outlet opening in the vehicle interior in front of the instrument panel orfarraumabdeckung.
- the gas generator next chamber can thus be used advantageously to move the remaining folded airbag package from the outer housing into the vehicle interior and to position it at a location favorable for further deployment below the outer housing.
- the gas generator next chamber ends in the filled state in the region of the outlet opening and preferably in the plane of the outlet opening, so that the remaining airbag package is placed just below the outlet opening before the remaining chambers of the airbag unfold along the instrument panel. In this way, the gas bag is safely moved around the edge of the outlet opening, without resulting in an unwanted force on the edge of the instrument panel.
- the gas generator next chamber may be disposed within the outer housing so that it at least partially fills and generates a directed out of the outer housing force on the rest of the airbag package.
- the gas generator next chamber for example, between the remaining airbag package and the rear wall of the outer housing to exert a defined force on the rest of the airbag package when filling.
- the chamber next to the gas generator is preferably arranged in the folded airbag package in such a way that, after the activation of the gas generator, in a first activation step, the chamber next to the gas generator first fills, while the remaining airbag package still essentially remains in the folded state.
- the force generated by the filling gas and the increase in volume of the gas generator next chamber is preferably directed substantially perpendicular to the plane of the outlet opening. This direction can coincide with the vertical when the knee airbag module is arranged in the vehicle at the lower end of the instrument panel and the plane of the outlet opening is substantially horizontal.
- the gas bag package is then moved in this activation step substantially perpendicular to the outlet opening without cross components would already arise along the instrument panel.
- the wall bounding the gas generator next chamber is formed so that it allows a flow connection between the gas generator next chamber and the adjacent chamber, wherein the entire gas flow should be made exclusively from the gas generator in the gas generator next chamber and from there into the directly adjacent chamber.
- the initially filled volume is limited by the wall of the gas generator next chamber and / or by the type of folding of the remaining airbag package.
- the gas bag package is preferably folded and the gas generator next chamber arranged so that the filling gas generated by the gas generator flows directly and completely first in the gas generator next chamber.
- the direct inflow can be assisted by the fact that the flow path within the gas generator next chamber is not crossed by a fold of the gas bag, a partition or a tether in the interior of the gas bag.
- Shape and volume of the gas generator next chamber can be interpreted so that the gas generator next chamber in the inflated state, the space within the outer housing substantially completely fills. It has been found that in this way, a force directed perpendicularly to the outlet opening can be produced in a well reproducible manner over the entire surface of the remaining airbag package.
- the wall which separates the gas generator next chamber and the remaining airbag package from each other in the inflated state of the airbag in the plane or substantially parallel to the plane of the outlet opening lies.
- the wall is formed by a constriction or a partition wall connected to at least one flow-through opening between the chamber next to the gas generator and an adjoining second chamber.
- the constriction can be generated, for example, by the shape of the blank parts of the gas generator next chamber and the directly adjacent second chamber.
- a simple measure for the production of the wall it is also to use a partition with flow openings between the gas generator next chamber and the adjoining chamber.
- the wall is formed by at least one tether extending in the interior of the gas bag, which connects two opposite outer wall sections of the gas bag and which limits a maximum distance between the outer wall sections.
- the tether preferably runs in the plane of the outlet opening in order to achieve a defined positioning of the remaining airbag package directly in front of the outlet opening in the initial activation phase.
- the wall may be formed so that it opposes a resistance to the inflowing filling gas, so that first the gas generator next chamber is filled and the remaining airbag package is still substantially folded. It is also conceivable to supplement the wall in the initial deployment phase by a fold of the gas bag package, which is arranged so that a further inflow of the gas into the remaining chambers only after the more or less complete unfolding of the gas generator next chamber is possible.
- a section of the outer wall of the gas bag could lie above a flow-through opening between the chamber next to the gas generator and the adjoining chamber.
- the gas bag has, for example, at least three chambers arranged one behind the other, the chamber next to the gas generator adjacent to a second chamber and the second chamber adjacent to a third chamber such that the gas bag has a curved shape when inflated overall. This allows the gas bag to follow the curvature of the instrument panel and to lay between the instrument panel and the knee-shin region of the vehicle occupant.
- the gas generator next chamber, the second chamber and the third chamber preferably include approximately a 90 ° angle, wherein the second chamber is in alignment with the interior of the outer housing.
- the second chamber may be separated from the third chamber by a partition provided with at least one flow opening, wherein the partition extends in the inflated state of the gas bag at an angle of about 0 ° - 30 ° to the vertical ,
- the chamber next to the gas generator preferably has a smaller volume than the adjoining second chamber in the inflated state of the gas bag, since the chamber next to the gas generator only serves for selectively pushing out the remaining gas bag in the initial activation phase of the knee gas bag module from the outer housing, while the subsequent second chamber also serves Retention effect can develop.
- Figure 1 is a schematic sectional view of a knee airbag module according to the invention according to a first embodiment, prior to activation;
- FIG. 2 shows the knee airbag module from FIG. 1 in a first activation step
- FIG. 3 shows the knee airbag module from FIG. 1 in a second activation step
- FIG. 4 shows the knee airbag module from FIG. 1, the airbag being fully deployed
- FIG. 5 shows a schematic sectional view of a knee airbag module according to the invention in accordance with a second embodiment with the knee airbag in the fully unfolded state.
- FIGS. 1 to 4 show a knee airbag module 10 of a vehicle occupant restraint system, not shown, according to a first embodiment.
- the knee airbag module 10 is disposed in an opening of an instrument panel 12 or adjacent a lower end of the instrument panel 12.
- the knee airbag module 10 has an outer housing 14, in which a gas generator 16 and a gas bag 20 that has been folded together to form a gas bag package 18 before deployment.
- An outlet opening 22 of the outer housing 14 for the gas bag 20 is closed by a cover 24 before the activation of the knee gas bag module 10.
- the cover 24 extends in extension of the instrument panel 12 and here abuts an edge 26 of the instrument panel 12, which may form either a lower end of the instrument panel 12 or an upper end of a recess in the instrument panel 12.
- the gas bag 20 is subdivided into a plurality of serially arranged chambers 28a-28f (see FIG. 4).
- the gas generator next chamber 28a also referred to as the first chamber 28a, connects directly to the gas generator 16 and receives as the first chamber of the gas bag 20, the gas flowing from the gas generator 16 filling gas.
- the gas generator next chamber 28 a is arranged so that the filling gas from the gas generator 16 flow directly into it can and immediately leads to an increase in volume of the chamber 28a.
- the chamber 28 a is not folded in and is placed directly between a back 30 of the outer housing 14 and the remaining airbag package 18.
- FIG. 1 shows the state of the knee airbag module 10 before activation.
- the cover 24 closes the outlet opening 22, and the airbag package 18 is received completely folded in the outer housing 14.
- the wall 32 which separates the gas generator next chamber 28a from the adjoining second chamber 28b is formed in this example by a shape-related constriction 34 between the chamber 28a and the chamber 28b, resulting from the shape of the individual blank parts of the airbag 20.
- the wall 32 could also be realized, for example, by a fabric part inserted into the airbag 20 with one or more flow-through openings which separate the chambers 28a, 28b from one another.
- the wall 32 lies in the plane of the outlet opening when the gas generator next chamber 28 a is fully inflated, and extends along the outlet opening 22 in this example.
- the wall 32 counteracts the flow of gas from the gas generator 16 to a flow resistance that results in complete inflation of the chamber 28a before the remainder of the airbag pack 18 begins to substantially expand. It is also conceivable that throughflow openings in the wall 32 in the first activation step are closed by the remaining airbag package 18, so that substantially no gas can flow into the remaining airbag 20 outside of the chamber 28 next to the gas generator.
- the filling gas generated by the gas generator 16 now also flows through the chamber 28a next to the gas generator into the second chamber 28b and unfolds it. From there, the gas continues to flow into the remaining chambers 28c to 28f so that the airbag 20 unfolds along the instrument panel 12 and inflates to its final shape.
- the volume of the inflated gas generator next chamber 28a is significantly smaller than that of the adjacent second chamber 28b.
- the second chamber 28b is arranged here in the inflated state directly below the gasgenerator next chamber 28a and is in alignment with the interior of the outer housing 14.
- the gas bag 20 in the inflated state describes a curved shape.
- the first three chambers 28a, 28b, 28c which are arranged approximately at a 90 ° angle.
- All of the chambers 28a to 28f are linearly fluidly connected to each other, wherein the supplied gas from the gas generator 16 can only flow from one chamber to the directly adjacent next and all gas first flows into the next gasgenerator chamber 28a. This is illustrated in FIG. 4 by arrows.
- the partition wall 40 between the second chamber 28b and the third chamber 28c is here in the fully inflated airbag 20 at an angle of about 0 ° to 30 ° to the vertical.
- FIG. 5 shows a knee airbag module 100 according to a second embodiment.
- the gas bag 120 is shown here only in its fully inflated form. However, it is, just as in the first embodiment, folded before the activation of the knee air bag module 100 to form a gas bag package in the interior of the outer housing 1 14, together with a gas generator 1 16.
- the wall 132 between the first chamber 88 a closest to the gas generator and the adjoining chamber 128 b is formed by one or more tethers which are arranged in the plane of the outlet opening 122 of the outer housing 14.
- the at least one tether which forms the wall 132, connects two opposite outer wall sections 150, 152 of the gas bag 120 and limits their spacing to the width of the outlet opening 122.
- the wall 132 provides a certain flow resistance which ensures that the first chamber 128a is inflated first and pushes the still folded, residual airbag package in front of it with a force perpendicular to the outlet opening 122 through the outlet opening 122 into the vehicle interior 38.
- the remaining gas bag 120 unfolds into the curved, inflated shape illustrated in FIG. 5 in which it lies between the instrument panel 12 and the knee / shin region (not shown) of the vehicle occupant. Due to the subdivision that provides the wall 132 at the level of the outlet opening 122, the gas generator near region of the gas bag 120 is tapered in the plane of the outlet opening 122, which additionally generates a force directed perpendicularly to the outlet opening 122.
- the chambers 128a, 128b may be formed by common outer wall blank parts.
- the subdivision into the individual chambers 128a, 128b can be carried out completely by the tether or tethers forming the wall 132.
- the wall 132 is also gas-permeable in this embodiment, so that the filling gas provided by the gas generator 16 can flow serially through all the chambers 128a to 128f.
- the tether which forms the wall 132 may for example have one or more flow-through openings, but may also be arranged in the interior of the gas bag 120 such that the gas can flow past the sides of the tether into the adjacent chamber 128b.
- the partition wall 140 between the second chamber 128b and the third chamber 128c is inclined at about 0 ° to 30 ° from the vertical.
- the essential features of the knee airbag module 100 match those of the knee airbag module 10 of the first embodiment.
- the tether forming the wall 132 is formed integrally with a portion of the dividing wall 140 between the second chamber 128b and the third chamber 128c. At the transition from the wall 132 to the partition 140, the tether is sewn to the gas bag wall.
