Abstract
The invention relates to an impact-absorbing garment and to an impact absorber used in it. The impact absorber has an inner surface and a impact-absorbing outer surface. The inner surface (4) bends into a concave shape more readily than does the outer surface (5). The impact absorber adapts readily to the shape of the garment in each case and allows for comfort also in other positions than one single position.
Description
PROTECTIVE CLOTHING AGAINST IMPACT
Background The invention relates to the clothing manufacturing technology and concerns impact-absorbing garments and impact absorbers used in these. The invention can be implemented for instance in the special garments of motorists.
l0 The purpose of impact absorbers in a motorist's driving gear, such as the garments of motorcyclists or snowmobile drivers, is to protect the most exposed parts of the body from slight injuries, typically fractures. Impact absorbers are covered by EN
1621-1 standard, which defines the parts of the body to be protected and the requirements posed on impact absorption.
Impact absorbers are usually located in pockets in the lining fabric of the garment.
They have usually been manufactured with a cup-like shape. It may be awkward to put on such protectors, because a limb may be caught in the impact absorber pocket or the lining fabric which is stretched by the impact absorber. The impact absorber may be uncomfortable during movement or in any other position than a special operating position. Plate-like, flexible impact absorbers have also been used.
So far, plate-like impact absorbers have the primary drawback of being stiff. Impact absorbers are generally made of a suitable resilient plastic material.
The discomforts of impact absorbers constitute an inconvenience understandable as such. Because of these discomforts, the wearer may even remove the impact absorbers from the garment, and then they naturally do not perform their task at all.
Description of the invention In accordance with the independent claims, a garment, an impact absorber used in it, and a method for manufacturing it have now been invented. The dependent claims describe some preferred embodiments of the invention.
In accordance with the invention, the garment comprises an impact absorber which bends into a concave shape inwards more readily than outwards. The impact absorber may have projections especially on its inner surface. The outer surface may also be provided with projections, the space between the projections on the inner surface being greater than the space between the projections on the outer surface. In this conjunction, the projections on the inner surface may for instance have a base thinner in cross-section or a top thinner than those of the projections on the outer surface, or the distance between the projections on the inner surface may be larger than that between the projections on the outer surface. The projections on the inner surface may have for instance the shape of a spherical calotte (hemisphere) or a hexagonal shape. The projections on the outer surface may be for instance rectangular or hexagonal in shape.
The purpose has been to develop an impact absorber which adapts readily to the shape of the garment in each case, which does not stretch the lining fabric and which allows both free movements and comfort also in other positions than one single position. The impact absorber also provides protection against impacts coming from different directions.
Some embodiments of the invention are described in greater detail below. The accompanying drawings pertain to the description. In the drawings figure 1 is a bottom view of a knee, elbow and shoulder impact absorber, figure 2 is a top view of the impact absorber of figure l, figure 3a shows the impact absorber of figure 2 in straight cross-section, figure 3b shows the impact absorber of figure 2 bent in cross-section, figure 4 is a bottom view of the left-side hip impact absorber, figure 5 is a top view of the right-side hip impact absorber, figure 6a shows the impact absorber of figure 5 in~straight cross-section, figure 6b shows the impact absorber of figure 5 bent in cross-section, figure 7 shows a motorist's driving gear, in which impact absorbers of the figures above have been placed.
The impact absorbers 1, 2 and 3 in the figures are made of a flexible and resilient material, preferably a plastic material apt for this purpose, such as polyurethane.
Approximately hemispherical projections 4 are provided on the inner surface of the impact absorbers. The projections on the inner surface are spaced from one another.
In the central area of the outer surface of the impact absorbers, projections 5 with an equal height but a larger width are provided at corresponding locations. The projections in the central area of the outer surface have been disposed in a rectangular array. They are rectangular in shape, and are disposed adjacent to one another. The outermost projections may be cut to a smaller size.

The impact absorber also provides protection against impacts coming from different directions.
Some embodiments of the invention are described in greater detail below. The accompanying drawings pertain to the description. In the drawings figure 1 is a bottom view of a knee, elbow and shoulder impact absorber, figure 2 is a top view of the impact absorber of figure l, figure 3a shows the impact absorber of figure 2 in straight cross-section, figure 3b shows the impact absorber of figure 2 bent in cross-section, figure 4 is a bottom view of the left-side hip impact absorber, figure 5 is a top view of the right-side hip impact absorber, figure 6a shows the impact absorber of figure 5 in~straight cross-section, figure 6b shows the impact absorber of figure 5 bent in cross-section, figure 7 shows a motorist's driving gear, in which impact absorbers of the figures above have been placed.
The impact absorbers 1, 2 and 3 in the figures are made of a flexible and resilient material, preferably a plastic material apt for this purpose, such as polyurethane.
Approximately hemispherical projections 4 are provided on the inner surface of the impact absorbers. The projections on the inner surface are spaced from one another.
In the central area of the outer surface of the impact absorbers, projections 5 with an equal height but a larger width are provided at corresponding locations. The projections in the central area of the outer surface have been disposed in a rectangular array. They are rectangular in shape, and are disposed adjacent to one another. The outermost projections may be cut to a smaller size.
When not in use, the impact absorber is plate-like. In use, the impact absorber tends to bend naturally in exactly the right direction, i.e. in an inwardly concave direction, because, during the bending of the impact absorber, the projections 4 on the inner surface are not pressed against one another and the incisions between the projections 5 on the outer surface open up. Thus, minimum force will be required for bending the impact absorber and for maintaining its shape. The impact absorber has the additional advantage of a smaller area in contact with the wearer's skin, thus causing less perspiration. The impact absorbers are also very suitable for particularly thick clothes, such as the driving gear of snowmobile drivers.
Owing to the protrusions 5 on the outer surface, the impact absorber also provides protection against impacts from different directions, although this is not even required under the EN1621-1 standard mentioned above.
The formability of the impact absorbers has been fiurther enhanced by means of cuts 6, 7 and 7' provided at the edges. Owing to the larger edge portions, the lateral areas have less flexibility than the central area, and thus the impact absorber will be well secured in its position in the pocket.
Holes 8 are provided at the angular sites of projections 4 and 5. The holes ensure better breathability, and also increase the flexibility of the impact absorbers.
The impact absorbers may be made of flexible, compressible cellular plastic, such as polyurethane. A piece having the required shape is cut from a plastic sheet, the spaces between projections 4 and 5 and any other protruding areas being formed by pressing or cutting. Finally the necessary cuts 6, 7, 7' and holes 8 are formed. A
suitable sheet thickness may be for instance in the range from 10 to 15 mm.
The flexibility of the impact absorber can be optimised by means of the shape of projections 4 and 5, of other projections, such as edge portions, and of grooves (and incisions) between these. The spring constant and impact absorption of the impact absorber can be acted upon primarily by means of the correct choice of material and material thickness.
The impact absorber 1 has approximately the shape of the sectional area of a split pear. The projections 4 and S axe located in the central area. Projections 4' are provided also in other areas of the inner surface. The parts around the central area of the outer surface form a plane relief surface. At the edge of the central area, radial cuts 6 have been provided to form strips 9. The cuts further increase the formability of the impact absorber. A central strip 10 and lateral strips 11 on its sides have been formed at the thinner end of the outer surface by means of longitudinal incisions.
Holes 8' are provided between the strips. The strips enhance the mouldability of the impact absorber around the limb part below the joint.
Impact absorbers 2 and 3 have the shape of an L. Projections 4 and 5 are provided over the entire area. The impact absorber is positioned with the long member on the hip joint and the short member on the front part of the hip bone. The short member has a cut 7 starting at its end, and at the angle between the members, a cut 7' parallell with the short member is provided, which extends slightly further than the cut 7. Thus the short member comprises two longitudinal strips 12. The long member tapers slightly towards the end. The outer angle of the members has been cut. The long member has holes 8.
The impact absorbers 1 to 3 mentioned above are easy to manufacture by pressing or cutting a sheet of suitable plastic material. When not in use, the impact absorbers require little space.
Figure 1 is a schematic view of a motorist's garment, in which the left side illustrates the front part and the right side the rear part. Zones 1 in the figure denote the parts of the body which are most exposed to impacts and in need of protection.
Impact absorber 1 is placed at the knees, elbows and shoulders, and impact absorbers 2 and 3 at the hips.
Owing to the protrusions 5 on the outer surface, the impact absorber also provides protection against impacts from different directions, although this is not even required under the EN1621-1 standard mentioned above.
The formability of the impact absorbers has been fiurther enhanced by means of cuts 6, 7 and 7' provided at the edges. Owing to the larger edge portions, the lateral areas have less flexibility than the central area, and thus the impact absorber will be well secured in its position in the pocket.
