    • In one embodiment the invention provides an impact-absorbing unit comprising an outer wear-resistant casing (10) and one or a plurality of inner stress resistant envelopes (20) containing impact absorbing material. The outer envelope is provided with a plurality of interconnection means (65,70) on at least one surface thereof, whereby a plurality of such units can be connected together in a closely adjacent relationship to define a substantially continuous surface. In another embodiment the compressible elements are directly enclosed within the casing 10. In another embodiment the loose fill of compressible elements is replaced by at least one open cell foam element and valve means are provided for evacuating air from the foam, whereby to compress the foam and allow subsequent expansion thereof by exposure to ambient air pressure.
    • 在一个实施例中,本发明提供了一种冲击吸收单元,其包括外部耐磨外壳(10)和包含冲击吸收材料的一个或多个内应力包封(20)。 外壳在其至少一个表面上设置有多个互连装置(65,70),由此多个这样的单元可以以紧密相邻的关系连接在一起以限定基本连续的表面。 在另一个实施例中,可压缩元件被直接包封在壳体10内。在另一个实施例中,可压缩元件的松散填充被至少一个开孔泡沫元件代替,并且提供阀装置用于从泡沫中排出空气,由此压缩泡沫 并且通过暴露于环境空气压力允许其随后的膨胀。
