Abstract

People in the ever faster moving vehicles, especially cars, need head-belts as a supplement to the usual body-seat belts. For head-belts with a rigid forehead-temples portion (2) is proposed for adaptation of the head-belt to the respective head size (4) of the person a device in which between the rigid front bar (2) and its padding (3) a bag-shaped , elastic bag (9) for inserting an adequately shaped fixed wedge (1) on both sides parietal of the head (4) is mounted. Instead of the fixed wedge (1), an air- and liquid-tight bag can be inflated with air or liquid, so that the padding (3) in each case the head (4) is applied.

Description

at The present innovation is a device for head-safety belts Vehicle occupants.

people in the ever-faster moving vehicles, especially cars, require head-belts as a supplement to the self-evident today Body safety belts. The previous solutions the head protection with the help of the airbags are only unsatisfactory, especially because airbags only up to an impact speed of 50 km / h successfully help. Also, glasses are on the face of the Motorists smash and cause airbags in rear-end collisions thus facial injuries.

As the German patent application with the file number 10 2005 045 025.3-22 from 12.9.2005 by Schmücker, the forehead half of the head-belt is a kind of cushioned hanger: The head-belt, which is approx. 2 cm wide, consists of a fixed splint with padding towards the forehead in its front half of the forehead. The foldable and latchable chin guard is attached to the fixed Stirnbügelteil via a hinge.

problem

Consists a head-belt from a fixed headband with buffering layer for Head side, so this headband can be either different wide radius, and then fits only one head size, so everyone Inmate his individual strap needed. The other solution proposed here is that the headband is so far Extensively designed, that all head shapes, no matter how big fit; but then it is for smaller heads a distance filler on both parietal areas of the head towards the fixed forehead bracket necessary; otherwise it would the head in the over-shaped headgear violently sideways in the accident strike and suffer injuries.

State of the art

The DE 196 04 822 A1 from 11.2.1996 by Nemerich refers generally to an airbag in a head helmet for a vehicle occupant, which is sensory inflatable in an accident. This creates a protective cushion between the head and the helmet or the head and the jacket.

task

the Subject of the application is the object of the free distance between a big, fixed headband of the head-belt and the individual head size of the individual Each person to fill in, so the braking forces in a rear-end collision, transfer it immediately and evenly to the head.

The The object is solved by the features of claims 1 and 2.

invention

The present innovation assumes that the approximately 2 cm wide head-safety belt in its front half consists of a fixed splint with padding to the frontal skin, as the German patent application with the file number 10 2005 045 025.3-22 of 12.9.2005.

According to the first embodiment the object of the invention is provided that the distance between head and fixed headband filled by it is that a suitably shaped wedge between the rigid end clip and its padding is pushed in from behind like in one Pouch which has a rubber-elastic stretch at the upper and lower edges is. This wedge, e.g. made of plastic, lifts the padding off the headband and pushes in between. This will be the original distance between padding and picked up too small a head. The wedge is designed in such a way that the upholstery is mainly parietal on both sides of the head has contact with the skin: the Head then also sits firmly on the side of the headband and can then at a Rear-end collision no longer receives lateral bruises.

To a further preferred embodiment the object of the invention is provided that the respective Person her head safety belt laterally adjusted on both sides by replacing the o.g. to be inserted or wedge to be introduced an air- and liquid-tight bag on the left or right parietal is attached to the temporal region, the by air or alternatively by a suitable liquid can be pumped, the pump piston / ball by hand or automatic pump with two supply hoses for left and right separated is trained.

To The overpressure can be used the bag over a valve mechanism can be drained arbitrarily.

The Invention is described in the following description with reference to in the attached Drawings illustrated schematically illustrated embodiment.

It demonstrate:

1 : Head safety belt with inserted wedge 1 parietal on both sides, top view,

2 : Cross section of the head-belt of the 1 at AA with implied head 4 ,

In 1 is the example of a head-safety belt viewed from above: In the direction of travel (arrow) is the rigid, hard front part 2 the head-belt with upholstery 3 to the head 4 provided. Outside the front bar 2 the belt pulls 5 , of the 8th leading backwards to the (not shown) headrest of the backrest of the seat. Between the hard forehead strap portion 2 and the upholstery 3 is the plastic wedge 1 in the elastic bag 9 Inserted from the back so far that the padding 3 on both sides parietal on the head 4 is applied. The entire head-safety belt does not slip when worn in normal driving and especially in the rear-end collision at high speed does not hit the head, but is immediately padded wide-area.

2 shows in cross section the example of 1 in the amount of the specified section line AA: The wedge 1 can be pushed in until the padding 3 the head surface 4 touched.

The preferred embodiment of the article of the invention has in place of the retractable wedges 1 on each head side with an air or liquid inflatable elastic, air and liquid-tight bag. Air or liquid is pumped in through a hose for each of the two bags with a pressure-dependent lock for each side extra. Depending on requirements, the overpressure in these bags can be released again after use.

• a) Säcke bei solchermaßen gebauten Kopf-Sicherheitsgurten größere Unterschiede des Kopf-Stirnbügel-Abstandes verschiedener Personen besser ausgleichen können als Keile,
• b) Luft im aufgeblasenen Sack gewichtsmäßig leichter ist als Keile aus festem Kunststoff und folglich die Ausführungsform mit den Luftsäcken am wenigsten gewichtsbelastend ist für Kopf und Nacken der Person,
• c) Säcke mit Luft oder Flüssigkeit ausführungstechnisch leicht über einen Großteil der Innenfläche des starren Stirnbügels aufgepumpt werden können. Dabei modellieren Säcke durch die gleichmäßige Druckverteilung die Polsterung sehr individuell dem jeweiligen Kopf an.

The advantage of this last preferred embodiment of the subject of the invention over the embodiment with the wedge is that

• a) Sacks in head restraints constructed in this way can better compensate for larger differences in the head-to-toe distance of different persons than wedges,
• b) air in the inflated bag is lighter in weight than wedges made of solid plastic and consequently the embodiment with the air bags is the least weight-bearing for the head and neck of the person,
• c) Sacks of air or liquid can easily be pumped over a majority of the inner surface of the rigid forehead bracket. Due to the even distribution of pressure, the bags shape the upholstery very individually to the respective head.
