Abstract
The air-bag 20 is associated with a strap 5 which extends between two anchoring points 11,7 on the A- and B-pillars respectively. The air-bag and strap are stored in a recess along the top of the door and along the A-pillar; the strap is therefore longer than the distance between the anchoring points 11,7. When the air-bag is inflated, parts of the strap are caused to follow a non-linear or convoluted path, applying tension to the strap. Either the strap can pass alteratively in front of and behind a plurality of cells 21,22,23... defined by the air-bag, as in fig.5 or the strap can be constrained to follow a zig-zag path within the interior of the air-bag as in fig.2. The air-bag is thus made rigid enough to protect the occupant even if the side window is broken during a side impact.
Description
DESCRIPTION OF INVENTION "IMPROVEMENTS IN OR RELATING TO AN AIR-BAG ARRANGENENT" THE PRESENT INVENTION relates to an air-bag arrangement, and more particularly relates to an air-bag arrangement in a motor vehicle such as a motor car.
It is known to provide air-bags in motor vehicles, such as motor cars, which air-bags are adapted to inflate in the event that an accident should arise, to provide protection for an occupant of the vehicle.
It has been proposed to provide an air-bag which, when inflated, is located between the head of an occupant of the vehicle and a window present in a door of the vehicle. The purpose of such an air-bag is to prevent the head of the occupant of the vehicle hitting the window and also to prevent the head of the occupant front emerging through the window opening if the window should be broken, or in the lowered position.
If the air-bag is to perform the desired function of retaining the head of the occupant in the vehicle when the window has been broken, an event which frequently arises during a side impact, the air-bag must have sufficient rigidity.
The present invention therefore seeks to provide an air-bag arrangement comprising an air-bag which, when inflated, possesses inherent rigidity.
According to this invention there is provided an air-bag arrangement for a motor vehicle, the air-bag arrangement comprising an air-bag adapted to be inflated in the event that an accident should arise and a strap, the strap having a first end secured to a first anchoring point and a second end secured to a second anchoring point, the length of the strap being greater than the linear distance between the anchoring points, the strap engaging the airbag or means associated with the air-bag so that, on inflation of the air-bag, the strap follows a non-linear path, the arrangement being such that when the air-bag is inflated, the strap is substantially tensioned.
Preferably the air-bag is formed of two layers of fabric which form, respectively, the front of the air-bag and the back of the air-bag, the strap having successive portions which are constrained to lie adjacent the fabric forming the front of the bag and the fabric forming the back of the bag.
Conveniently the strap passes through the interior of the air-bag and is constrained to lie adjacent the fabric forming the front of the bag and the fabric forming the back of the bag at selected points.
Advantageously the means provided to restrain the belt to lie adjacent the fabric forming the front of the bag and the back of the bag, comprise one or more internal loops provided within the air-bag, the strap sliding freely through the loops.
In an alternative embodiment the air-bag is divided into a plurality of cells which extend substantially parallel to each other in a direction transverse to the axis of the strap, the strap passing in front or and behind successive alternate cells.
Preferably the cells are separated by webs, the belt passing through an aperture formed in each web between each adjacent pair of cells.
Conveniently the air-bag, when inflated, is located across a door opening provided in a motor vehicle, the airbag being positioned substantially in alignment with a window opening present in a door provided in the door opening.
Preferably the length of the combination of the bag and the strap is greater when the bag is uninflated than when the bag is inflated.
Advantageously said one end of the strap is located adjacent the top of the "B"-Post of the motor vehicle and said other end of the strap is located at a point on the "A"-Post of the motor vehicle.
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 perspective view of one embodiment of the invention when the air-bag is inflated,
FIGURE 2 is a sectional view taken through the embodiment of Figure 1,
FIGURE 3 is an enlarged view of part of the interior of the air-bag of Figures 1 and 2,
FIGURE 4 is a perspective view corresponding to
Figure 1, but illustrating an alternative embodiment of the invention,
FIGURE 5 is a sectional view taken through the embodiment of Figure 4,
FIGURE 6 is an enlarged view of part of the air-bag shown in Figures 4 and 5, with part cut away for the sake of clarity of illustration.
Referring initially to Figures 1 to 3 of the accompanying drawings, one embodiment of an air-bag arrangement is illustrated. The illustrated air-bag arrangement incorporates an air-bag 1 which, when in the inflated condition (as shown) extends across a door opening 2 defined by a motor vehicle. The door opening 2 is intended to accommodate a door, and the door would have a window 3 as indicated in phantom.
The air-bag 1 is initially retained within a recess which extends across the top of the door opening, the recess being provided with a cover 4. In an initial condition of the air-bag arrangement, the air-bag and an associated strap (which will be described in more detail below) will be received within the recess and will be covered by the cover 4 so as to be unobtrusive. In the event that an accident arises and the air-bag is inflated, the air-bag 1 occupies the position illustrated in Figure 1 where the air-bag is located in the region of the top part of the door opening 2.
It can be seen that the air-bag 1 comprises a single chamber bag which is associated with a strap 5. The bag is made of fabric which defines the front of the bag directed towards the interior of the vehicle - and the back of the bag - which lies adjacent the window. The strap 5 has a first portion 6 which is connected by means of a bolt or other fastening 7 to part of the monocoque shell of the motor vehicle at an anchoring point adjacent the top of the "B"-Post 8 of the vehicle. The strap 5 includes a further strap portion 9 which is located within the interior of the bag. A final strap portion 10 is provided which extends from another part of the bag and is connected by means of a bolt or other fastening 11 to an anchoring point on the "A" -Post of the door opening 2.
The strap 5 must have sufficient length to extend across the top of the door opening and along the "A" -Post when the bag and the strap are initially stored within the recess. Consequently, the strap has a length which is greater than the distance between the bolt 7 and the bolt 11.
As can be seen from Figure 2 and Figure 3, the strap 9 extends across the interior of the air-bag 1, when it is inflated, in a zig-zag manner. The strap 9 passes through a plurality of securing loops such as the securing loop 12 shown in Figure 3, which effectively constrain successive portions of the strap to lie adjacent the fabric forming the front of the bag and the fabric forming the back of the bag, on the interior of the bag 1, at successive points on opposed sides of the bag. It is preferred that the portion 9 of the strap 5 within the bag 1 can slide freely between the loops 12, but one or more predetermined points of the strap may be secured substantially permanently to selected points on the interior of the bag 1 to provide an equivalent effect.
It is to be understood that as the air-bag 1 is inflated, the portion 9 of the strap 5 within the interior of the bag is caused to adopt the non-linear or convoluted path constituted by the zig-zag configuration which is illustrated in Figure 2, thus effectively "shortening" the strap and causing the strap to be tensioned or tightened.
Thus, even though the strap in its relaxed state has a length which is greater than the distance between the bolts 7 and 11, because the portion 9 of the strap occupies the zig-zag configuration of Figure 2, nevertheless the strap is tensioned, and consequently imparts a degree of rigidity to the air-bag when in the inflated state.
The shape of the portion of the strap which has the zig-zag configuration and the shape of the bag together with the pressure of gas in the bag determine the tension applied to the strap when the bag is inflated. The greater the tension, the greater is the rigidity of the bag. If the bag is very rigid, it will be able to withstand a substantial force.
Thus, the air-bag serves to minimise any risk of the head of the occupant of the vehicle moving outwardly through the opening provided for the window 3, even if the glass forming the window has been broken.
Figures 4 to 6 illustrate a second embodiment of the invention. Those features of the two embodiments which correspond are identified by corresponding reference numerals and will not be re-described in detail.
In the embodiment of Figures 4 to 6 the air-bag 20 is formed of a plurality of discrete cells 21 to 25, which are separated by webs of fabric 26 to 29. The cells and the webs provided between the cells extend substantially vertically. Each web of fabric, such as the web 26 which is shown on an enlarged scale in Figure 6, is provided with an aperture 30.
It can be seen that the strap 5 has regions which pass in front of certain cells, such as the region 31, which passes in front of the cell 21 and the region 32, which passes in front of the cell 23. The strap has other regions, such as the region 33 which passes behind the cell 22 and the region 34 which passes between the cell 24.
Thus, the strap passes alternately in front of and behind adjacent cells, the strap thus having successive portions that are constrained to lie adjacent the fabric forming the front of the bag and the fabric forming the back of the bag.
The cell 21 is provided, at the edge adjacent the "B"-Post 8, with a flap 35 that defines a further aperture 36 through which the strap passes.
It is to be appreciated that the strap 5 has an initial length which is greater than the linear distance between the bolts 7 and 11, thus enabling the strap and the air-bag to be stored within the recess provided for that purpose which extends above the door opening. When the air-bag is inflated, because the strap is caused to follow a non-linear or sinuous path which alternatively passes in front of and behind the adjacent cells of the air-bag, as can be seen in Figure 5, a tension is applied to the strap, making the air-bag itself substantially rigid.
Whilst the invention has been described with reference to two embodiments, it is to be appreciated that many modifications may be effected within the scope of the invention.
The embodiments of air-bag described above may be manufactured with a one-piece weaving technique. Separate layers of fabric which form the front and rear of the airbag are woven simultaneously and in pre-selected areas the threads from the two layers are inter-woven so that effectively in these areas, a single integral layer is formed.
Whilst air-bags in accordance with the invention have been illustrated, as extending across a single window opening, it is to be appreciated that air-bags in accordance with the invention may find other applications where it is desired to provide a substantially rigid airbag which is, effectively, self-supporting. For example, an air-bag in accordance with the invention may be provided which, when inflated, is located adjacent the window in both the back door and the front door of a motor vehicle.
Alternatively, an air-bag in accordance with the present invention may be provided which extends transversely across the passenger cabin of a motor vehicle at a location adjacent the backs of the seats provided for the driver and front passenger. Such an air-bag may minimise the risk of a rear passenger being thrown forwardly and through the windscreen of a vehicle.
