The Γ is non-inflatable but naturally air at any time. The air cushion is formed by a Γ blown by a blow molding machine for blowing flexible containers or bottles, and there is a vent hole for natural air to enter. It becomes an air cushion. It consists of a soft hollow container and a stopper that "plugs the blown port of the hollow container into a non-inflatable air cushion". Industrial applicability The invention can provide any buffer effect and industrial utilization value. Detailed description of the invention '.

The first object of the present invention is an air cushion (air bag) which is free of inflation but naturally air at any time. The air cushion (air bag) mainly includes a blow molding machine (also called a hollow molding machine for blowing soft containers or bottles). ) The blown air is formed to allow natural air to enter ", a soft hollow container (see symbol 1 in Fig. 2 or symbol 2 in Fig. 3), and a" plugged in the hollow container for blowing by the blow molding machine " It is composed of a stopper (see Fig. 4) formed by a blow port formed by air blow.

The hollow container, which is used to blow the blown air from the blow molding machine (see symbol 5 in Fig. 2), is sealed by the stopper (Fig. 4) to retain only "the natural air can enter at any time" To the inside of the hollow container so that the hollow container becomes an air-filled but naturally airless cushion at any time, and when the air cushion, that is, the hollow container, is hit, the gas in the air cushion is released Some small holes to improve the cushioning function of the air cushion, which are also the "intake and exhaust" ventilation holes (see symbol ^{2 2 in} Figure 4).

5 The small hole, that is, the ventilation hole 22 is located in the center of the plug (Figure 4).

The small hole, that is, the ventilation hole 22, can be replaced by a "hole located in another appropriate position of the hollow container", that is, the "intake and exhaust" ventilation hole, and the blown port 5 is replaced by Sealed up.

The second object of the present invention is to separately install two (see FIG. 1 symbols 1 and 2) airbags (airbags) of the "inflatable ⁽¹ but naturally airy) at any time" to the driver's seat belt (Please refer to symbol 3 in FIG. 1) to protect the driver's chest and abdomen from the front and back, so as to prevent the driver's chest and abdomen from directly colliding with the steering wheel of the car when the car collides, or go Avoid the driver's chest and abdomen being injured by the seat belt.

The two air cushions (air cushions) that are free of inflation but naturally air at any time are the front and back of the seat belts of the passengers who are attached to the car by 5 devices, so as to avoid the passengers when the car collides The chest and abdomen were struck directly or injured by the passenger's seat belt. The blown port 5 is located at one end of the hollow container and has a flange (see symbol 6 in FIG. 2). The other end of the hollow container has a "laterally extending and has a small portion J like the flange (see Fig. 2 symbol 8) J (see Fig. 2 symbol 7).

The two "inflatable but naturally air-filled" air cushions (airbags) 1, 2 are respectively mounted to the driver or passenger by two pairs of T-shaped connectors (see Figures 5 and 6). The front and back surfaces of the seat belt 3 are overlapped. Each pair of the two pairs of T-shaped connectors is to hold one end of each of the two air cushions 1, 2 so that the two air cushions 1, 2 are mounted on the driver or the passenger's seat belt. Each of the two pairs of T-shaped couplers (Figs. 5, 6) is a flange (see Fig. 2, symbols 6 and 8) for one end of each of the two air cushions 1, 2 ) De-embed its rectangular slot (see symbol 9 in Figure 6) so as to hold each end of each of the two air cushions 1, 2 tightly. The two heads of each pair of T-shaped connectors (see Figures 6 or 5 symbols 10, 11) are covered by two grooved rubber connectors (see Figure

8) Hold together the driver or passenger's seat belt. The two grooved rubber connectors (Figures 7 and 8) are supplied to one end of each head of each pair of T-shaped connectors (Figures 5 and 6 with the symbol 1 (1, 11) to be inserted so that The ends 10, 11 of the heads of each pair are bundled together so that the first of each pair of T-shaped connectors (Figs. 5, 6) is stacked.

At the end of the first of each pair of T-shaped connectors, there is a short post (such as the symbol 12 in Fig. 5) for insertion into the upper and lower holes of each of the two rubber connectors (see Figures 7, 8 (13, 14) to more securely fix the two grooved rubber connectors.

The two sides of the first rectangular slot of each of the two pairs of T-shaped connectors have a gap on one side (for example, symbol 15 in Fig. 6) for supplying the hollow container of each of the two air cushions. The blown port 5 and the tibial portion of the laterally extending small part 7 (see symbols 16 and 17 in FIG. ² ) are de-embedded, so that the flange (Flang 8) is de-embedded in the rectangular groove.

There are several holes at the bottom of the two air cushions and short posts "for inserting the holes separately" (see symbols 18, 19, and 21 in Fig. 3), so as to shorten the number skills. Columns 2 d and 21 are inserted into the holes 18 and 19 to prevent the two air cushions I and 2 from moving.

The bottom of each of the two air cushions 1, 2 or at least the bottom of one of the two air cushions has 13 long parts (see Figures 2 and 3, symbol 2 GA, 2 DB), so as to provide the seat belt 3 to be embedded and Stabilize the two air cushions on the seat belt.

The plug (Figure 4) has a "ventilation and exhaust" ventilation hole (this is the ventilation hole, symbol 4 in Figure 4) in its central part to enhance the "free inflation but naturally at any time The cushioning function of the air cushion (airbag) is that when the air cushion is hit or compressed, the internal air will release some from the ventilation hole 22 so that the air cushion can absorb "the impact force that hits the air cushion" And it has a higher cushioning function, so the air cushion can not only absorb the impact force, but also improve the bearing capacity of the air cushion to withstand the impact force. Each of the two pairs of T-shaped connectors has a hole "opposed to the ventilation hole" (see symbol 23 in Fig. 1) for allowing the natural air to enter the air cushion when it is struck The vent hole 22 allows the gas released from the vent hole to pass through.

Before the driver or passenger uses the two air cushions 1, 2 for the first time, the seat belt is buckled as it was originally and then the two pairs of T-shaped connectors are used (Figures 5, 6) Go and hold the two air cushions to the seat belt; then adjust the two air cushions to the proper position in front of the chest and abdomen of the driver or passenger, and finally unfasten the seat belt; by the above method, the two air cushions Will be installed in the seat belt at any time; when the driver or passenger wishes to use the two air cushions 1, 2 as long as the seat belt is buckled as before, the seat belt does not have to be used again. For T-connectors (Figures 5 and 6), the driver or passenger naturally uses the two air cushions. When the seat belt is unfastened without having to be used, the buckle of the seat belt (see figure!) Is de-hook to "located on one of the two pairs of T-connectors or on the two air cushions" One of the appropriate locations (Figure!) Is the symbol ² 7) "for the hook (see Figure ^{9 for the} symbol ² 5). After the seat belt is unwound without having to be used, the two air cushions are erected against the side of the backrest of the driver's or passenger's seat (see figure!) Symbol Π or 29). Each of the two T-shaped connectors (Figures 5 and 6) and the hook 25 are made of a suitable soft plastic material.

The two air cushions 1, 2 are further attached to the driver or passenger separately. When the driver is going to drive the car or when the passenger has just taken the car, the driver or passenger can be fastened automatically. " The front and back of the automatic safety belt to protect the chest and abdomen of the driver or passenger.

A third object of the present invention is to place the air cushion device in a proper position of the car, so that when the car collides, the car or persons inside the car can be prevented from being directly hit, so as to reduce the risk of the car or the people in the car. hurt.
