Description

The invention relates to providing passive safety for drivers and passengers of vehicles, and in particular to seat belt systems, especially for an adjustable spring-loaded seat.

The seat belt at which the ends of the seat belt tags are attached to the vehicle body creates a problem in positioning the seat belt lock relative to the seat when adjusting the seat in the vertical or horizontal direction.

Known anchor seat belt adjustable seat. Belt anchor point,

used on the seat, the position of which can be adjusted in the longitudinal and vertical directions, is removed from the floor of the vehicle compartment and can move relative to the floor. It is located on the guide of the upper movable frame of the seat and moves with the frame in the vertical direction, but remains stationary when the frame is moved in the longitudinal direction. The guide is connected to the front end of the swing rod, the rear end of which is connected to the floor or to the rear wall of the passenger compartment

Such a technical solution is metal-intensive, as well as unreliable in operation, so

as it remains possible that the guide may be jammed, the Big disadvantage is that when adjusting the seat in the longitudinal direction, the bracket where the belt of the waist belt is fastened changes its position relative to the seat.

The closest technical solution adopted for the prototype is a seat belt consisting of a section used to secure the seat to the seat and a section used to connect the seat to a part of the body relative to which the seat can move within certain limits. The section connecting the seat to the body is connected to the remaining section of the seat belt using the adjuster and the strap. A tag fastening with one end to the lock and the second end by means of a fastening element to the car body passes through the regulator.

If the specified limits of relative movement of the seat and body are exceeded during overloads, the controller releases the seat and the parts of the seat belt are disengaged (see for the taste of U.S. No. 3890002, 1975).

This design has several disadvantages: firstly, it requires additional material costs to strengthen the seat, and secondly, under heavy loads, the movement of the seated person is quite long due to the freely located part of the handle between the controller and the point of attachment of the handle in the vehicle body ,

The purpose of the invention is to increase reliability and safety in long-term operation.

This goal is achieved by the fact that in the seat belt, mainly for an adjustable spring-loaded seat containing a lock, a lock, an emergency-locking retractor (AZVU), a tie, one end of which is attached to the lock and the other to the bracket fixed to the body of the vehicle, the ha is made elastic in the form of a loop, both ends of which are fixed in the regulator loosely located on it. In order to provide additional security in extreme situations by fixing the lock, the lock is located in the pocket of the shock-absorbing bracket mounted on an adjustable spring-loaded seat .. ".

Fig. 1 is a perspective view of a seat belt for an adjustable spring-loaded seat in an unfastened position; figure 2 is a view from the side of the castle and the tabs with the regulator.

The seat belt (see Fig. 1) contains a tab 1, passed through the guide 2, through the eye 3 with the tongue 4 and equipped with an eye 5, fixed to the floor of the body, an emergency locking retractor (AZVU) 6, lock 7. thrust 8 about the regulator 9. Guide 2 at point 10,

0 and AZVU at point 11 is fixed to the sidewall of the vehicle body (not shown in Fig.). Hook 8 is made in the form of a loop (see, Fig. 2), both ends of which are fixed in the regulator 9 freely located on it,

5 One end of the loop 12 of the link 8 is sewn to the plate 13 of the regulator 9, and the other end of the loop 14 of the link 8 passes through the regulator 9 around the plate 15. The upper part of the loop of the link 8 passes through the fixed eye 16

0 in the lock 7, and the lower part of the loop of the link 8 passes through the eye 17 fixed by a bolt 18 to the bracket 19. The bracket 19 is attached to the body floor at the point 20 of the vehicle.

5 The position of the lock 7 is fixed

with the help of the shock-absorbing bracket 21 secured to the frame 22 of the seat 23. The lock 7 is located in the pocket 24 of the shock-absorbing bracket 21,

0 The use of the proposed seat belt is as follows. In the idle position, the position of the adjustable spring-loaded seat 23 for the user is selected using

5 by adjusting it in the longitudinal or vertical directions. Based on this, with the help of the regulator 9, the required length of the link 8 is adjusted between the lock 7 and the lower attachment point 20 so that it would be selected

0 slack tape.

In the working position, tongue 4 is inserted into lock 7. When rolling the adjustable spring-loaded seat, the 23 mark 1 is pulled out respectively from the AZVU 6 or

5 volts is drawn into the interior of the ABCU 6.

Thus, the proposed vehicle belt has a number of advantages, namely, it is more reliable and safe, since during operation it reduces the movement of the seated relative to the adjustable spring-loaded seat in emergency situations.

The use of elastic traction makes it possible to choose the maximum

5 when adjusting the seat, and in extreme situations it softens the blow due to its elasticity to the user. Fixing the lock in the pocket of the shock-absorbing bracket allows you to fix its most secure location, in

at the same time, in extreme situations, it does not injure the user, and during normal operation the flexible system allows to increase the durability and reliability of the belt. The presence of such a thrust also allows the use of static belts without a HAZA. which reduces material costs and reduces the cost of the belt.
