Abstract
The airbag housing 24 is supported by a plurality of resilient supports 16 extending from a mounting point on the housing to frame 8 attached to the steering wheel 1. The resilient elements comprise (Fig. 3) a bell shaped elastomer body (33) having a bore through which a rivet (38) passes such that element compression or deformation permits limited axial and lateral damped displacement of the housing relative to the wheel. The frame 8 forms part of an electric hom circuit, closed on housing axial movement by electrode pairs 20, 21 that accompany the mounting elements. The damped lateral movement alters the vibration characteristics of the steering wheel.
Description
"Improvements In Or Relating To An Airbag Arrangement"
THE PRESENT invention relates to an airbag arrangement and more particularly relates to an airbag arrangement comprising an airbag unit mounted on the steering wheel of a motor vehicle.
It has been proposed previously to provide an airbag mounted within the hub of the steering wheel of a vehicle, the airbag being adapted to be inflated in the event that an accident should occur in order to provide some protection for the driver of the vehicle.
Typically the airbag, and an associated gas generator, is provided in a housing, and the housing is mounted as an integral unit on the hub portion of the steering wheel.
When a vehicle is in motion the chassis may be subject to vibrations. These vibrations may be transferred to the steering wheel of the vehicle through the steering column.
The vibrations of the chassis of the motor vehicle exhibit a frequency dependent amplitude profile, the profile being different for different vehicles. A typical profile often has a high amplitude in the region of a frequency of 30Hz. A steering wheel without an airbag unit typically has a resonance frequency of about 50Hz which means that when a steering wheel without an airbag unit is used in connection with a typical chassis, the vibrations of the chassis are not transferred to the steering wheel.
However, it has been found that a steering wheel which is provided with an airbag unit will, due to its relatively high mass, have a resonance frequency of about 30Hz.
Subsequently the resonance frequency of a steering wheel with an airbag unit may be substantially equal to a frequency at which the chassis may exhibit high amplitude vibrations. Thus there is a risk that, due to resonance effects, a steering wheel provided with an airbag unit may vibrate laterally with a high amplitude.
It has been found that by permitting the airbag unit to move laterally by a small distance, for example between 0.5 and 0.8mm, against a suitable spring or damping force, the steering wheel may be provided with two resonant frequencies instead of a single frequency, those frequencies typically being approximately 20 and approximately 45Hz. The precise resonance frequencies depend upon various factors including the spring force. It is also to be appreciated that the amplitude of the vibrations of the steering wheel could be reduced by incorporating a component that exhibits a damping force effectively connected between the airbag unit and the steering wheel.
It is desirable to enable the airbag unit to move axially, relative to the axis of the steering shaft, in order to activate the horn of the motor vehicle. It has therefore been proposed to mount an airbag unit on a support plate in such a way that the airbag unit can move laterally relative to the support plate against a spring force, and then to mount the support plate, together with the airbag unit, on the main body of a steering wheel so that the support plate can move axially against another spring force acting between the base plate in the steering wheel. However, this arrangement is relatively complex.
The present invention seeks to provide an improved airbag arrangement.
According to this invention there is provided an airbag arrangement, the airbag arrangement comprising a steering wheel adapted to be mounted on a steering column, and an airbag unit mounted on the steering wheel, the airbag unit being mounted on the steering wheel by a at least three of resilient support means which extend first mounting points fast with the steering wheel to second mounting points on the airbag unit, the resilient support means being adapted to permit axial movement of the airbag unit relative to the steering wheel in a direction substantially parallel to the axis of the steering column and also to permit limited displacement of the airbag unit relative to steering wheel laterally with respect to the axis defined by the steering column.
Preferably the limited lateral movement is limited to a distance of between 0.5 and 0.8mm.
Conveniently, the support means exhibit damping properties such that the maximum amplitude of the displacement of the airbag unit in normal driving conditions is 0.2 to 0.3mm.
Advantageously, the axial movement is a movement of between 0.5 and 1.5mum.
Preferably, four said resilient support means are provided.
Conveniently, an arrangement according to any one of the preceding claims wherein a fixing frame is provided which is secured to the steering wheel, the fixing frame defining said first mounting points which are fast with the steering wheel.
Preferably, an arrangement according to any one of the preceding claims wherein each of said resilient means comprises a resilient element which extends between one of said first mounting points formed fast with the steering wheel and one of said second mounting point provided on the housing forming part of the airbag unit, one mounting point comprising an aperture receiving one end of the resilient element, that end of the resilient element being provided with a relatively large diameter bore therethrough, the resilient element being adapted to be compressed to permit said axial movement and being adapted to be distorted to permit said lateral movement.
Advantageously, the other mounting point is provided with a rigid element extending through the bore at least as far as said aperture, the rigid element engaging the inner wall of the resilient member in the region of said aperture when the housing has been moved laterally, to limit the degree of lateral movement.
Preferably, the rigid element comprises a rivet having one end secured to said other mounting point, the rivet having a portion of enlarged diameter located between the said other fixing point and said aperture, part of the resilient member being trapped between the enlarged diameter portion of the rivet and the said other fixing point.
Conveniently, electrode means are provided, at least one electrode means being carried by the airbag unit and at least one electrode means being located at a position fast with the steering wheel, the electrode means being located so that on axial movement of the housing the said electrode means carried by the airbag unit may contact the said electrode means fast with the steering wheel.
Advantageously, the resilient element is made of an elastomer.
Preferably, the electrode means are so configured that the electrode means will contact each other on axial movement of the housing when the housing has been displaced laterally to the fullest possible extent.
Advantageously, the electrode means comprise a plurality of pairs of cooperating electrodes, one electrode of each pair having a substantially dome-shaped operative surface and the other electrode of each pair having a recessed operative surface, or a planar operative surface.
In order that the invention may be more readily understood, and so that further features thereof may be appreciated, the invention will now be described, by way of example, with reference to the accompanying drawings in which:
Figure 1 is a diagrammatic sectional view of an airbag arrangement comprising an airbag unit in position on the hub of a steering wheel,
Figure 2 is an underneath plan view of the mounting plate and frame of the airbag unit illustrated in Figure 1,
Figure 3 is an enlarged view of part of the arrangement shown in Figure 1,
Figure 4 is a view corresponding to Figure 3 showing the illustrated components in one relative position and;
Figure 5 is a view corresponding to Figure 3 showing the illustrated components in an alternate relative position.
Referring initially to Figure 1 a steering wheel 1 is provided with a plurality of spokes 2 extending from a hub portion 3. The hub portion 3 defines a central recess 4 on the side of the hub which is opposed from the steering column.
A plurality of bosses 5 extend inwardly, from the hub portion 3, into the recess 4, each boss 5 having an axially extended threaded bore 6 adapted to receive the shank of a fastening screw 7. The fastening screws 7 serve to connect, to the bosses 5, a fixing frame 8.
The fixing frame 8, as can be seen most clearly in
Figure 2 is of a "U-shaped" form, comprising a linear base portion 9 and two spaced-apart parallel arms 10, 11. Each arm 10, 11, is provided with a centrally located inclined circular lug 12, 13 defining an aperture to receive the associated fixing screw 7.
Each arm 10, 11, is provided with two spaced-apart support structures 14,15,16,17 of identical construction, which will be described hereinafter in greater detail.
Thus four support structures are provided located at the corners of a notional square or rectangle. In an alternative embodiment three support structures may be provided located at the corners of a notional triangle, and in other embodiments five or more support structures may be provided.
Each arm 10, 11, is also provided with two horn switch electrode combinations 18, 19, 20, 21, which will again be described hereinafter.
The base portion 9 of the frame 8 is provided with a projecting element 22 adapted to receive an electrical connector so that the frame 8 can form part of an electric circuit.
The support structures 14,15,16,17 support, above the frame 8, a base plate 23, of substantially square configuration. The base plate 23 forms the bottom part of a housing 24 incorporating a cover 25 extending over a chamber 26 which accommodates a folded airbag 27.
Contained within the folded airbag is a gas generator 28.
Part of the gas generator extends through an aperture 29 formed at a central position in the base plate, and the gas generator 28 is secured to the base plate 23 by means of bolts 30 located at positions which surround the aperture 29, part of the airbag 27 being trapped between the gas generator 28 and the base plate 23.
The cover 25 of the housing 24 comprises an inner structural layer 31 formed of a relatively hard plastic material provided with one or more lines of mechanical weakness 32, defining one or more "doors" adapted to open when the airbag is inflated. The layer 31 is provided with an outer covering 33 of a relatively soft material.
Figure 3 illustrates, in greater detail, the support structures 16 and the associated electrode combination 20 in an initial condition. The other support structures and electrode combinations are of a similar form.
At a position adjacent an inner edge of the frame 8 there is a recess 31 formed in the frame. There is an aperture 32 formed in the base of the recess. The aperture forming a mounting point which is fast with the steering wheel. A resilient support member 33 is provided, fabricated of an elastomer material. The support member 33 is substantially bell-shaped configuration having a relatively large diameter lower region 34, with a bore 35 extending through it. Within the upper region of the support member the base 35 is of relatively small diameter, and in the lower region of the support member the bore is of a larger diameter.
The lower region 34 of greater diameter is provided, on its exterior, with a peripheral annular groove 36, the groove 36 receiving the part of frame 8, which defines the periphery of the aperture 32 in the recess 31.
The resilient support member 33 is thus positioned to extend upwardly above the mounting point provided in the recess 31.
A rivet is provided having shank 38 which passes through the inner bore 35 of the resilient support member 33. The lower part of the rivet passes through the part of the resilient member 33 received i the aperture 32. The rivet has a radially outwardly extending base 39 located at a position beneath the resilient member and has a shank portion 40 of enlarged diameter which engages the interior of the bore 35 at a position adjacent the lower end of the smaller diameter portion of the bore. The upper end of the rivet 38 is secured, by means of a conventional dome-end 41, to the base plate 23, at an upper mounting point. The upper portion of the resilient member 33 is effectively trapped between the portion 40 of enlarged diameter of the shank 38 of the rivet and the undersurface of the support plate 23.
The electrode combination 20 comprises a lower electrode 42 which is mounted on the frame 8, lower electrode 42 defining, on its upper surface, either a planar surface or a part-spherical recess. The support plate 23 carries a second electrode 43 in the form of a rivet having a substantially spherical lower head 44 which is aligned with the lower electrode 42.
Turning now to Figure 4, if a downward force is applied to the housing 24, the entire housing 24 will move downwardly, with a movement which is parallel to the axis of the steering column. The movement may be a movement over a distance of 0.5 to 1.5mm. If a force is applied to one corner of the housing that corner will move downwardly with a movement which is substantially parallel with the axis of the steering column. The resilient support member 33 will become compressed. The lower substantially spherical part 44 of the electrode 43 will be brought into engagement with the lower electrode 42 carried by the plate 8, thus completing an electric circuit incorporating the frame 8 and the support plate 23. This may for example, activate the horn or hooter of the motor vehicle.
When the downward force is removed from the housing 24 the resilient member 33 will revert to its original configuration, as shown in Figure 3, thus returning the housing 24 to its initial position.
It is to be appreciated that the nature of the resilient support members is such that the base plate 23 can move laterally relative to the axis of the steering column, with a side-to-side movement by a limited extent, thus permitting a restricted range of movement for the base plate 23, that movement being a movement of between 0.5 and 0.8mm. However, the movement is a movement against a damping force provided by the support members and thus the movement is a damped movement. Thus the greater the speed of movement of the airbag unit relative to the steering wheel, the greater the damping effect will be. Typically the resilient members 33 exhibit damping properties such that the maximum amplitude of the displacement of the housing 24 relative to the steering wheel 1 under normal driving conditions is in the range of 0.2 to 0.3mm.
As can be seen from Figure 5, as this movement is executed, the lower part of the resilient support member 33 becomes distorted, with the shank 38 of the rivet 38 moving to one side of the relatively large diameter part of the bore 35 provided in the resilient member 33. The movement is terminated when the shank over the rivet 38 begins to compress that part of the resilient member 33 which is located between the wall of the relatively large diameter part of the bore 35 and the annular groove which is provided on the exterior of the resilient member 33.
It is thus to be appreciated that in the described embodiment of the invention the airbag unit is supported, relative to the hub of the steering wheel, by resilient mounting means adapted to permit an axial movement of the airbag unit relative to the hub of the steering wheel, in a direction substantially aligned with the axis of the steering column, and which also permit a lateral movement of the airbag unit relative to the hub of the steering wheel. The lateral movement will be a damped movement, thus minimising "resonance" vibrations of the steering wheel. The resilient support members extend directly from a component that is fixed in position relative to the hub to the airbag unit without an intermediate support plate.
The airbag unit may be manufactured together with the resilient support members and the fixing frame. This assembly may be mounted easily on the steering wheel hub.
