DE3937648C1 - Shock absorbing motorcycle suit - has pads each having air-tight envelope with foam in-fill - Google Patents

Abstract

An impact neutralising buffer for protecting the human body includes an air tight cushion with a plastics foam material filling, which is moulded to the shape of the body component. The filling consists of a plastics foam insert, which has smaller pores over a section of the component, as a result of partial evacuation of the cushion. The filling consists of a section of a plastics foam mat. ADVANTAGE - The device has good damping characteristics and takes up minimal space.

Description

The invention relates to a shock neutralizer to protect human Body parts with one in the shape of the one to be protected Body part-fitted, airtight pillow with a Plastic foam existing filling.

A shock neutralizer of this type for a piece of work clothing is known from DE 84 21 062 U1. These shock neutralizers are preferably in particularly vulnerable places, e.g. B. in Knee area, the garment arranged around these places Protect against bruises and abrasions when falling.

These are sufficient for protective clothing for motorcyclists known shock neutralizers, because they are a significant Had to have volume to be expected in the event of a fall To be able to approximately intercept shocks. This would also result in that the protective clothing in the area of shock neutralizers voluminous and therefore not particularly attractive.

It is an object of the invention to provide a shock neutralizer to create the kind of protective clothing mentioned above has particularly good damping properties and yet occupies only a relatively small volume.  

This object is achieved according to the invention in a generic shock neutralizer in that the Filling consists of a plastic foam insert,  which by partially evacuating the pillow underneath Reduction of the pores brought to part of their size is.

The invention uses the size reduction of the pores to increase the damping property of the plastic foam. The starting material can be fine-pored Plastic foam can be used. By evacuation the pores are reduced to a level similar to that of foaming are not producible at all. The size of the pores is up to a minimum size but the decisive parameter for the properties of the plastic foam. The smaller the pores are, the more energy it takes Plastic foam when deformed. With the Evacuation is also the size of the plastic foam Insole reduced in size, which means the integration of the shock neutralizer in protective clothing not only simplified, it is for that correspondingly less space required.

Further expedient and advantageous embodiments of the Invention emerge from the subclaims.

A particularly expedient embodiment provides that the Filling is a blank of a plastic foam mat. Alternatively, the filler material can be a variety of fine-pored plastic foam beads or Foam particles exist. The main advantage of second embodiment is that the evacuated Pillow can be deformed as needed, being the one you want Maintains shape until the impact neutralizing forces be exercised. Open pore plastic foams are well suited for these shock neutralizers because the air they take in is easy to evacuate can escape.  

Because the shock neutralizer as a unit in protective clothing can be integrated, it can be damaged or damaged Destruction can be easily replaced.

An embodiment of the invention is based on the drawings explained in more detail. It shows:

Fig. 1 shows a cushion-shaped Stoßneutralisator prior to evacuation,

Fig. 2 shows the shock neutralizer of Fig. 1 after the evacuation and

Fig. 3 is protective clothing for motorcyclists with indicated shock neutralizers.

In the exemplary embodiment according to FIG. 1, an approximately rectangular blank 12 of a plastic foam mat is introduced into a plastic pillow 10 designed as a bag. The cushion 10 is suctioned off at the opening 11 and then closed by welding. A fine-pored plastic foam is chosen. The pores 13 are accordingly small and the plastic foam is open-pore.

When evacuating, care is taken to ensure that only the thickness of the plastic-foam blank 12 changes, as shown in FIG. 2. The pores 13 are significantly reduced and thus also the property of the plastic foam. The plastic foam thus evacuated and reduced in size absorbs shocks much better, since high energies are required to deform it. With its reduced size, the shock neutralizer therefore still has excellent damping properties and offers good protection for areas of the body covered with it. The filling of the cushion 10 consisting of plastic film can also contain fine-pore open-pore plastic foam balls or foam particles.

In Fig. 3, protective clothing for motorcyclists with shock neutralizers 14 to 21 is shown. The protective clothing - here a one-piece suit - consists of the upper part 6 and the lower part 8 . The upper part 6 has shock neutralizers 14 , 15 and 16, 17 in the area of the shoulders and the elbows , while in the lower part 8 the shock neutralizers are arranged in the area of the hips and knees. In the area of the shock neutralizers 14 to 21 , the protective clothing has cavities into which the pillow-shaped shock neutralizers 14 to 21 can be inserted. A captive arrangement of the shock neutralizers 14 to 21 can, for. B. be produced in that they can be connected or covered with the inner part of the protective clothing by means of a zipper.

The shock neutralizers shown in FIG. 2 can also have other shapes which essentially depend on the locations of the jacket or suit for which they are intended.

To protect the knees, the pillows are e.g. B. rather oval and the Adjusted shape of the knees.
