Abstract

When shock acts on a helmet which a driver of a motorcycle or the like wears, rotational component as well as advancing component of the shock can be absorbed effectively. In a helmet with a shock absorbing liner fitted on an inner side of a shell , a layer of elastic body for absorbing shock having a component directed along an outer surface of the shell is provided between the shell and the shock absorbing liner or between an outer layer of the shock absorbing liner and an inner layer of the shock absorbing liner .

Description

The helmet
Technical field
The present invention relates to for example helmet worn of motorcycle or racing driver of vehicle.
Background technology
Everybody knows the helmet now, announces the disclosed helmet among the flat 6-240508 as Japanese publication.In this helmet, at shell be embedded between the impact absorbing pad in the shell or placed the enhancing fabric of doing with reinforcing fiber between the two-layer impact absorbing pad, and it is fixed on shell and the impact absorbing pad, so that obtain the thickness of improved shock absorbing capability and don't increase shell.
Act on load on the helmet and roughly can be divided into direction facing to the load at helmet center and depart from the tangential load in this center (rotative component).Two kinds of loads all can be absorbed by the deformation of lining etc. in ordinary helmet.
Summary of the invention
The present invention proposes a kind of helmet that can effectively absorb this rotative component.
The invention provides a kind of helmet for this reason, the impact absorbing pad and one that it has a shell, to be arranged on the inboard of shell absorbs elastomer layer, above-mentioned impact absorbing pad is made with an outer lining and an inner liner on the inner surface that is fitted in shell, this absorption elastomer layer is arranged between above-mentioned outer lining and the above-mentioned inner liner, it is characterized by: above-mentioned outer lining and above-mentioned inner liner have a branch cleaved surface that forms a spherical surface betwixt, and outer lining and inner liner can slide relative to one another along this minute cleaved surface; And
Above-mentioned absorption elastomer layer is a gel layer, and its allows branch cleaved surface along above-mentioned sphere between lining and the impact absorption inner liner relative slip to be arranged impact absorption outside, and absorbs the impact with a rotation component of force.
According to the present invention, because it is not fixed to one another wearing the head and the shell of personnel selection, so when impulsive force acts on the helmet from the outside, it is the component of acceleration of direction perpendicular to outer surface of outer cover that this helmet not only can absorb the reach acceleration, is the component of acceleration of direction along outer surface of outer cover but also can absorb rotation acceleration.
Description of drawings
Fig. 1 is the vertical cross-section diagram of first embodiment of the invention;
Fig. 2 is the vertical cross-section diagram of second embodiment of the invention;
Fig. 3 is the vertical cross-section diagram of third embodiment of the invention;
The specific embodiment
Fig. 1 is a vertical cross-section diagram, and the first embodiment of the present invention is shown.Head ash 20 has the impact absorbing pad 22 that the shell 21 that obtains by injection-molded nylon and styrene bubbles are moulded work, and this absorption pad is fitted in and is bonded in the inboard of shell 21.This impact absorbing pad 22 is separated into outer lining 23 and inner liner 24, and its minute, cleaved surface was along sphere 26 extensions.In this embodiment, absorb elastomer layer 25 and be configured between outer lining 23 and the inner liner 24, and be adhered to two impact absorbing pads 23 and 24.
Also be because the head of helmeting is not fixed in shell 21 in this embodiment, so when impulsive force when the outside acts on the helmet, it is the force component of direction perpendicular to shell 21 outer surfaces that this helmet not only can absorb the reach force component, is the force component of direction along shell 21 outer surfaces but also can absorb the rotatory force component.In this embodiment, because point cleaved surface between lining 23 and the inner liner 24 is the ball surface outside, and absorb elastomer layer 25 along this sphere configuration, so outer lining 23 and inner liner 24 easy relative slips, and the change of the free degree of rotation direction is big, thereby can absorb the rotatory force component of impulsive force effectively.
Fig. 2 is a vertical cross-section diagram, and the second embodiment of the present invention is shown.The helmet 30 has the impact absorbing pad 32 that the shell 31 that obtains by injection-molded polypropylene and styrene bubbles are moulded work, and this absorption pad is fitted in and is adhered to the inboard of shell 31.This impact absorbing pad 32 is separated into two-layer by parting plane, this parting plane 36 extends along ball surface, and absorbs elastomer layer 35 and be configured between outer lining 33 and the inner liner 34, and is bonded on these linings.In this embodiment, on the edge of inner liner 34, form outside flange 34C.
The effectiveness of present embodiment is identical with the effectiveness of above-mentioned first embodiment.When yet lining 33 and inner liner 34 relatively forwarded certain limit to outside, flange 34C just ran into the edge of outer lining 33, rotated thereby prevent excessively.
Though flange 34C can be formed on the edge of inner liner 34 outwardly, flange also can form on the edge of lining 33 outside inwardly, makes this flange run into the edge of inner liner 34.
Fig. 3 is a vertical cross-section diagram, and the third embodiment of the present invention is shown.The helmet 40 has shell 41 and impact absorbing pad 42, and this absorption pad is fitted and is adhered to the inboard of shell 41.Impact absorbing pad 42 is divided into outer lining 43 and inner liner 44 by parting plane, and this parting plane extends along ball surface 46.In this embodiment, form recess 43a outside on the part of lining 43, and form protuberance 44b on the part of this recess 43a, make this protuberance 44b can embed recess 43a in facing toward of inner liner 44.
According to this embodiment, inner liner 44 normal conditions are fixed in outer lining, to stop by absorbing the unnecessary motion that elastomer causes, but when having direction along the impact force action of the component of shell 41 outer surfaces during in the helmet, protuberance 44b just is damaged, allow to move, thereby can absorb this component of impulsive force.The institute that present embodiment certainly reaches above-mentioned first embodiment produces effect.
With top opposite, can on inner liner 44, form recess, and form protuberance on the lining 43 outside.Also can form many to protuberance and recess.
In the above-described embodiments, in the scope that does not influence above-mentioned effect, the inside part ground of lining can be connected the outside of shell, so that ventilation.
