SI22710A - Collision safety system in means of transportation - safe seat - Google Patents

Abstract

A collision safety system in means of transportation - a safe seat - is based on a movable seat. This is enabled by a damper installed between the seat and the undercarriage. Consequently, the safety belt must also run from the backrest back to the seat because of this.

Collision safety system in vehicles with secure seats

The subject of the invention

The subject of the invention is a special mechanism (shock absorber) that is mounted between the seat and the chassis in all vehicles.

A technical problem

A technical problem solved by the invention is how to upgrade the seats in all vehicles to make them significantly more secure in the event of a frontal collision (or rear-end collision).

The prior art

No seat in the vehicle has a mechanism which, in the event of a collision (from the front or rear), allows the seat to slid in a controlled forward position a little forward or backward. All seats are fixed to the car body, and in the event of a collision, such seats do not provide additional safety. The seats as we know them so far in the vehicles are static. This means that in the event of a collision, they remain in the same place depending on the vehicle body. Due to the static of the seat, the collision time is shorter, which in turn means more personal injury.

The solution to a technical problem

The seats, supplemented by a special mechanism (shock absorber), significantly prolong the collision time, and thus can many times save human life or. significantly mitigate personal injury.

The invention of a safe seat therefore substantially eliminates the disadvantage of static and fixed seats in a fairly simple way. This is done by installing a special force absorber under the seat. In the event of a frontal collision, the seat will not stop at the same time as the vehicle, but will slide forward in a controlled manner (see Figure 5). In this way, the collision time is prolonged and at the same time much of the energy released is transferred to the force absorber, which significantly reduces injuries. It is similar in the case of a rear-end collision.

The essence and construction of the invention, and thus the operation of the security system, will be further explained by a description of the embodiment and the accompanying figure, in which FIG. 1 is a perspective view of a secure seat from the side of the invention; FIG. 2 is a perspective view of the rear seat rear seat of the invention, FIG. 3 is a top view cross section of a roller with a movable disc without a spring for damper construction, FIG. 4 is a cross-sectional view of a shock absorber with added springs according to the invention; FIG. 5 shows the operation of the safety system (shock absorber) in the event of a frontal collision; 6 is a cross-sectional view of the damper, which protects us only in the event of a frontal collision, FIG. 7 is a seat safety scheme where a seat belt extends from seat to seat.

A key role in the safety system (secure seat) is the integrated shock absorber, which is shown in Figure 3, Figure 4 and Figure 6, between the seat and the chassis.

Figures 1 and 2 show the appearance of a secure seat according to the invention. The aforementioned figures show that the shock absorbers shown in FIG. 4 and FIG. 6 are attached to the lower body of the vehicle via the anchorages 6 on the lower side and attached to the seat via a disk 2 and anchorage 5. shown in Figures 3, 4 and 6, is constructed from:

1) along the top of the section of the hollow cylinder 1 (the cylinder is closed on each side),

2) left and right moving discs 2 and

3) two springs 3.

The task of the disc 2 is of a practical nature, since it makes it easier and more compact to attach the seat to the damper. Figure 2 shows the final appearance of the invention from the rear, where on each side of the damper (Figure 4) there are guides 4 from the seats, which are no novelty and can remain the same as for static seats. However, it is important that the guides 4 provide good seat sliding.

The damper as shown in Figure 4 is intended for front and rear collisions. It could be rearranged to be just for frontal collisions. Such a scheme is shown in Figure 6. In this case, the seat would slide further and thus protect us further from damage, since the collision time would increase even more and release more energy on the spring. Such a system requires more space due to the sliding of the seat forward, otherwise serious injuries to the legs can be sustained. Part of this could be solved with newly designed dashboards where more space is allocated to the legs.

The invention brings another important change. The seat belt must no longer extend from the vehicle body to the vehicle chassis, but from the seat to the seat, as shown in Figure 7. Otherwise, the seat belt would inhibit the sliding of the seat in the vehicle and thus prevent the shock absorber (Figure 4 and Figure 6). , to take on some of the harmful energy for us, thereby protecting drivers or passengers.

The damper system shown in Figure 6 is especially highly recommended in those vehicles where we want to further increase safety and at the same time when we have another passenger. The shock absorber in Figure 4, in the event of a rear-end collision, can have a fatal impact on the passenger behind us (the seat slides backwards in relation to the chassis), since it can primarily damage his legs if there is insufficient space.
