  Flexible protective helmetUSPTO Application #: 20070226881Title: Flexible protective helmet Abstract: A protective helmet having an inner hood includes a spacer knitted fabric of a monofilament yarn. The hood is covered by a pneumatic central layer which can be pressurized by means of compressed air and can be inflated by means of an air pump which can be, for example, removed and provided with valves. An outer layer consists of an inner textile layer which lies over the pneumatic central layer, and plates which are fixed to the textile layer, for example by adhesion. The plates include, for example, of plastic, composite materials, or natural materials. The plates can be arranged in such a way that joints are created thereinbetween, the outer layer thus being provided with a certain elasticity in order to cater for different head shapes and sizes.

BACKGROUND OF THE INVENTION [0001] 1. Technical Field [0002] The present invention relates to a flexible protective helmet. [0003] 2. History of Related Art [0004] Several flexible protective helmets are familiar. [0005] Their invention concept in general comprises creating a protective helmet that when not in use can be folded to save space and on the other hand, due to its shape and size, when in use is identifiable as a protective helmet. This as such should increase its acceptance. [0006] Several such protective helmets that can be folded have become familiar, for instance, from WO 00/57739 (D1), WO 01/24651 (D2), EP 0 802 741 (D3) and EP 1 332 688 (D4). [0007] Among the protective helmets mentioned here, the one for cyclists, disclosed under D1, is designed in modular concept and is thus foldable and can be dismantled, however, it is clearly identifiable as a protective helmet when in use. Space saving in a folded state is rather insignificant. [0008] The protective helmet according to D2 consists of an inner layer made of shockproof material that is disintegrated into truncated butt-joined or interlocked teethed pieces. This layer of shockproof material is covered with a textile and elastic material on the outside and inside. Due to this, when worn it feels more of a cap. The possibility of folding it is restricted due to the shape of the shockproof inner layer. [0009] The protective helmet that is familiar according to D3 features a cap-shaped design, whereby this cap is made of numerous, preferably six, spherical segment-shaped pieces, which are preferably made of foamed plastic. Among themselves, for instance, these segments are connected by means of ribbons. [0010] The protective helmet according to D4 is again made in modular concept and based on the desired intensity or type of head protection it can be complemented in modular manner. [0011] Whereas the ones according to D1 and D4 only partially fulfil the tasks, the ones mentioned in D2 and D3 are more relevant to the present invention without fulfilling the requirements for the ability of being folded or put aside on the one hand and fulfilling the acceptance requirement on the other hand. SUMMARY OF THE INVENTION [0012] The task to be solved by the present invention is the creation of a collapsible or foldable protective helmet for sportspersons, which provide optimum protection for the chosen type of sports and at the same time which is not prima-vista apparent as a protective helmet. [0013] The solution of the posed task is reproduced in the characteristic part of Claim 1 with respect to its main characteristic, and in the following claims with respect to further advantageous embodiments. BRIEF DESCRIPTION OF THE DRAWINGS [0014] A more complete understanding of the flexible protective helmet of the present invention may be obtained by reference to the following Detailed Description, when taken in conjunction with the accompanying Drawings, wherein: [0015] FIG. 1 shows a longitudinal section through an innermost layer; [0016] FIG. 2 shows a longitudinal section through an innermost and a middle layer; [0017] FIGS. 3-6 show different embodiments for the middle layer, in schematic plan views; [0018] FIG. 7 shows a longitudinal section through an inner, a middle and an outer layer; [0019] FIG. 8 shows an embodiment of an outermost layer in a schematic longitudinal section; [0020] FIG. 9 shows a further embodiment of an outermost layer in a schematic longitudinal section; and [0021] FIGS. 10-11 further show embodiments of the outermost layers in a schematic longitudinal section.
