Definitions
- the present invention relates to a motor vehicle safety system, in particular a safety system which protects against whiplash injuries.
- the car occupant's head is then thrown forward whilst the upper part of the body is restrained by the seat belt.
- the neck is subjected to a sudden flexural stress which may result in another injury in the neck region.
- whiplash injuries are a major problem both for the individual and for society.
- the individual suffers a lot of pain and often loss or reduction of capacity to work.
- this causes loss in the form of an additional strain on the health service and loss of earnings.
- whiplash injuries mean enormous losses in the form of compensation and so forth.
- Norwegian Patent Application No. 942861 relates to a headrest containing a net drawn out by telescopic release bars. This net is soft and cannot give the seat occupant any protection other than to catch his head and prevent it from being thrown forward in the event of a crash impact from behind.
- a safety device for attachment to a seat in a vehicle for restricting the movement of a person's head relative to the vehicle on extreme acceleration or retardation as a result of the crash impact, comprising a netting (3) or the like, which on release can be rapidly deployed in front of the person's head, where the netting (3) in its first position, the pre-operative position, is stowed in a headrest behind the head of the seat occupant, and in a second position is located in front of the seat occupant's head.
- the vehicle occupant will not be hampered by the safety device during normal driving, but will be protected effectively against the injuries which may occur in the event of a crash impact from behind.
- Figure 1 is a frontal view of one embodiment
- Figure 2 is a bird's eye view of the same embodiment as in Figure 1, in the released position;
- Figure 3 is a lateral view of the same embodiment as in Figure 1 ;
- Figure 4 is a lateral view of a partial section of the same embodiment as in
- Figure 5 shows the section A-A in Figure 1 ;
- Figure 6 is a frontal view of the same embodiment as in Figure 1 in a released state
- Figure 7 illustrates the same embodiment as in Figure 1 , retained by means of elastic stays.
- the safety device in the illustrated embodiments is constructed in the form of a headrest which can be secured to the standard attachment means of a seat back with the aid of bars 16.
- the illustrated headrest is indicated by an outer shell 1, in which there are provided hoops (2), which in the pre-operative position are drawn inside the headrest, but which in the released position swing out therefrom.
- hoops (2) are provided in the device, two on each side of the device, one in the upper edge and one in the lower edge, which in the pre-operative position lie inside the device, but which when the device is released, can be pushed outward and forward, so that the hoops (2), which are curved, form a ring forward of the device, one ring at the top of the device and one ring at the bottom thereof, in front of the head of the seat occupant.
- Forward pieces (4) on each side of the device extend between the upper and lower hoops (2) on each side.
- the forward pieces (4) are preferably padded in order to avoid injury on impact of the forward pieces (4) against the seat occupant's head and face.
- the distance between the hoops (2) is defined by the length of the forward pieces (4).
- a netting (3) which is connected to the hoops (2).
- an elastic body (7) such as, e.g., an elastic band
- a locking dog (8) which is attached to an inertia release device (10).
- the release mechanism in this illustrated embodiment is an inertia release device which is based on the inertia in a weight provided at one end of an arm (18) which is pivotally mounted about an axis (19) on a bracket (20).
- a spring (15) is provided to hold the weight (10) in its fixed position.
- a locking arm (21) projects approximately perpendicular to the arm (18), preferably close to the shaft (19).
- the inertia of the weight (10) causes the weight to swing forward and backward and thus draw the locking pin out of engagement with the projection (9).
- the hoops (2) will thus be released from lock, and will be brought forward and out of the head rest by means of the elastic bodies (7).
- a release means is provided on either side of the headrest, i.e. one release means for each pair of hoops.
- the release devices may be connected, or other types of release devices may be used to ensure a simultaneous release on both sides of the headrest.
- the hoops (2) are pulled forward and retained in this position after release by an elastic body (7), preferably an elastic band.
- This elastic body can, as shown in Fig. 5, run over several rollers (11).
- the illustrated headrest has an inner shell (12) which can be drawn out by the inner shell when it is subjected to a sufficiently large load.
- the inner shell (12) is attached to a point of attachment in the outer shell (1) by means of two or more straps (14). These straps are preferably elastic and are of limited extendibility. In the event of a crash impact from behind, the device will thus be released so that the person's head is held by the hoops and the net which are swung forward in front of the head. When the head is then flung forward, the inner shell and the hoops accompany the head, and the head experiences a gentle, controlled retardation with the aid of the straps (14) with their limited extendibility and concomitant incorporated elasticity. The limits or prevents neck injuries.
- the inner shell can be pushed back inside the outer shell, the hoops (2) with netting (3) can be reinserted inside the headrest, and the device is once more ready for use.
- a resilient and preferably inflatable cushion 17.
- the head In the event of a collision which releases the device, the head is pressed back against this cushion, compressing it whilst the hoops (2) are swung forward. When the pressure of the head against the cushion ceases, this again expands and helps to hold the head in place in the device.
- the inner shell may be mounted directly, for example, on another headrest, seat back or the like, and can be detachable from this base with the same types of straps as shown in the device having in an inner and an outer shell, to check the movement of the head forward in a manner which will cause minimum injury.
