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.
- 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 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 5 shows the section A-A in Figure 1 ;
- 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.
- 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 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.
