    • DESCRIPTION OF THE RELATED ART
  • In prior art engineering helmets, as shown in FIGS. 1-3 , primarily comprises a shell 1 having a plurality of fixing components 11, i.e. rivets with general quantity of 4 or 6, evenly distributed inside the shell, a head band 3 configured inside the shell 1 in a ring shape, a plurality of suspension straps 4, capable of interlaced fitting with a circular band or a cushioning 2, wherein two ends of the suspension straps 4 connecting with the head band 3 respectively via a clip 41 and an adjusting component 42 to position the head band 3, and a chin strap (not shown in the figure).
  • The upper end of the foregoing clip 41 is secured to the upper end of the adjusting component 42 via a rivet 43, the adjusting component 42 is capable of moving flexibly so that the clip 41 is aligned to the fixing components 11 of the shell and then snap. The suspension straps 4 respectively pass through the openings of the clip 41 and the adjusting component 42 from bottom to up, fold backward and fixed via sewing. Therefore, the clip 41 is enabled to connect with the adjusting components 42 and meanwhile covers and hides the rivets 43 inside and is more closed to the shell 1.
  • According to the above description, the combination structure of the suspension straps 4, the clips 41 and the adjusting components 42 in prior art engineering helmet enables the suspension straps 4 and head band 3 to have flexible elasticity, while the shell 1 is suffering from the front, back, left and right sides impact, the elasticity of the head band 3 and the suspension straps 4 are not sufficient to effectively absorb the impact force, thus seriously reducing the safety and protection of the engineering helmets. An improvement is expected.
    • SUMMARY OF THE INVENTION

  • To achieve the above-mentioned objective, the engineering helmet comprises a shell having a plurality of fixing components, a head band installed inside the shell, a plurality of suspension straps connected to the head band and two ends of the suspension straps each having a clip and an adjusting component respectively snapped with the fixing component and the head band of the shell, and a chin strap, characterized in that a buffer installed inside each end of a plurality of suspension straps, meanwhile the buffer being secured to the clip and the adjusting component to enhance the absorbing of impact force from the shell, thereby improving the protection and safety of the engineering helmet.
  • According to the above-mentioned engineering helmet, the buffer is composed of the shock-absorbing materials, namely, EVA, TPE, TPA, TPC, TPO, TPS, TPU, TPV, etc.
  • According to the above-mentioned engineering helmet, preferably, the buffer is secured to the clip and the adjusting components in a manner of adhesion.
  • According to the above-mentioned engineering helmet, the inner side of the buffer has an adhesion agent, i.e. a double-sided adhesive or a strong glue.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a structural view of a conventional engineering helhet.
  • FIG. 2 is a sectional view of a conventional engineering helmet.
  • FIG. 3 is a partial enlarged sectional view of a conventional engineering helmet.
  • FIG. 4 is a sectional view of the present invention.
  • FIG. 5 is a partial enlarged sectional view of the present invention.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • By way of example, the invention is further explained with respect to a preferred embodiment shown in the drawings and the features and advantages will become apparent from the following description of the invention which refers to the accompanying drawings.
  • Referring to FIGS. 4 and 5 , the present invention comprises a shell 1, a head band 3, a plurality of suspension straps 4 and a chin strap (not show), wherein the inner side of the shell 1 has a plurality of fixing components 11, a plurality of suspension straps 4 are evenly distributed inside the shell 1 and connected to the head band 3, two ends of the suspension straps 4 respectively have a clip 41 and an adjusting component 42. However, the said structures are prior art and no further description is made herewith.
  • The primary feature of the present invention is that a buffer 5 is configured inside each end of a plurality of suspension straps 4, the buffer 5 is composed of a shock-absorbing material, i.e. EVA, TPE, TPA, TPC, TPO, TPS, TPU, TPV, etc.
