Abstract

An automatic safety helmet and cover protection can be worn on the back, mainly of people who play sport. The protection device is stored in a rucksack casing (3) and is attached to back straps (4-6). The casing accommodates essentially a guard (11-19), a drive member and a control mechanism. There is storage space in the center for various implements. By triggering a spring accumulator (40.1, 40.2), the protection device is rotated, in the event of a threatening fall, into an erect protective position in fractions of a second by way of a trigger cord or by automatic actuation due to a sensor (23). The protective position is held at the top by a toothed catch member (7.1, 7.2). Mating toothing on the catch member maintains the protective position even in the event of a change in direction.

These

P bars

12,13,14,15,16,17,18,19 that constitute the U type are together used pivotal mounting, and its front end position is positioned in two reinforcements 8.1,8.2, is fixed on simultaneously on the guide post (20) in the case tooth disk 7.1,7.2 is housed.P bar 11 connects with tooth disk 7.1,7.2 is arranged securely.

In the resting position that it is represented visibly, protective device is approximate to be parallel to the back and to lay, thereby the P bar is placed in the case 3.By the resting position of this setting, it can make progress and overturn 220 ° forward nearly, so this device has just reached the position that covers head that raises, as shown in Figure 5.For realizing the swinging operation of protective device between its resting position and rising protective position, in case 3, place two preloaded springs 40.1,40.2.

For ejecting protective device, a magnetic switch 21 is arranged in the bottom of case, when drop that the sportsman causes danger, control this magnetic switch by sensor 23.By pulling out the removable locking pin 22 in the magnetic switch 21, the protective device of locking just unclamps automatically, and P bar 11 releases are subsequently also launched the top rapidly under the effect of spring pressure.This sensing mechanism is known as rolling rod in automobile making.The variation at its response inclination angle and acceleration and deceleration.

From Fig. 3, as can be seen, chest comprises the mold pressing shell 24 that an extreme that is contained on the body stretches, and can be made of plastics in 4,5,6,7 and 8 the expression.For optimizing weight, mold pressing shell 24 can cut between reinforcement 28, and is sealed by the knapsack fabric.

In Fig. 4 and 6, can see back(-)up

belt

4,5,6 and the reinforcement 28 of magnetic switch 21, and the slide fastener in the knapsack cover 29, this slide fastener plays the inlet effect that enters shelf space 44, as shown in the figure.

Shown in the side half-sectional view of 1: 1 ratio of Fig. 8, reinforcement 28 is connected with 8.2 with reinforcement 8.1 with the left side on the right side, and these two reinforcements play support guide bar 20 and pass through in top cross.

Fig. 8 represent rotatably mounted have disk 30 and a security positioner 31 tooth disk 7.2 arranged.Be also shown in preloaded spring 40.2 among the figure, it is attached on the guide rod 20 and is bearing in the center of reinforcement 33 and hangs over outside on the P bar 11.Preloaded spring and guide post are separated from shelf space simultaneously by cover 48.

Since only P bar 11 with tooth disk 7.1 is arranged; 7.2 connect securely; and remaining bar is owing to the reason in space; then also stagger mutually with pivotal mounting; remaining bar is joined to one another by fabric strip 9; in the tension of chest outside, as shown in Figure 5, a facial guard bar 10 turns to facial the place ahead by stopping power control from P bar 11 to this fabric strip by P bar 11.Spring 32 is pressed in facial guard bar 10 on the P bar 11, works up to the control that forces.

Tooth disk 7.1,7.2 is arranged simultaneously when guide post 20 rotates when the P bar launches the top, ratchet 34.1,34.2 overcomes its acting force of the spring a little outwards to be put, thereby has tooth disk 7.1,7.2 to turn over ratchet 34.1,34.2 in the mode of ratchet.When P bar direction is opposite (accident or load), there be the tooth of tooth disk 7.1,7.2 and ratchet 34.1,34.2 to play locking action immediately one.The transmission of power appears by pin 47.Reinforcement 45.1,45.2 connects at some points with reinforcement 8.1,8.2, and also as the bearing of ratchet and pin.

Because preceding P bar 11 is locked by tooth disk 7.1,7.2 is arranged, back

P bar

16,17,18,19 drives and props up latch simultaneously, and P bar 12 to 19 is being remained on the distance of setting by fabric strip 9 before the inflection.P bar 19 for example, is supported to have leaned against on the tooth disk 7.1,7.2 by extension arm 49.

In order to prevent

P bar

11,16,17,18,19 collide its terminal location excessively suddenly, in stopper region the buffer element 35 of shock-absorbing can be installed, and for example this terminal location can comprise an elastomeric material.

Possible mistake is discharged, and ratchet 34.1,34.2 can overcome its spring force mentions by two openings of shell 24 and the foamed plastics 50 and the stylus pin 36 of the right and left, after chest takes down, can be clear that very much from Fig. 7.Therefore the whole protecting device can be pressed into chest 3, is on the crown spring 43 up to magnetic switch 21 again.

As another selection of the contact position on the chest 37, can use the contact position 38 on the saddle equally, thereby increase the security that discharges.When the people when a certain displacement of saddle is opened, mechanically open magnetic switch 21 by the release rope 39 of guiding on the adjustable pitch circle dish 42 that clamps, protective device begins to work simultaneously.
