BG111107A - Protective device for passengers in car - Google Patents

Abstract

The protective device is designed to protect passengers from injuries, including the driver of the car during a frontal impact. The design of the protective device could be easily mounted and geared to existing cars. The protective device consists of a platform (1) consisting of an U-shaped metal base (2), on the underside of which is provided a support frame. To the platform (1) are borne rollers (5), guided in rails (6) which are arranged in the longitudinal direction of the car and are secured to the floor (7) of the car. On the base (2) are mounted in a known way the front seats (8) and rear seats (9). The front seats (8) are mounted on the rails, with the possibility of adjustment of their position in the longitudinal direction. Between the rear seat (9) and the trunk of the car is provided a certain distance, which determines the maximum movement of the platform (1) onto the rails (6). The platform (1) is rigidly connected at the front by bars (10), which are themselves fixed tothe bumper (11) of the car.

Description

TECHNICAL FIELD

The invention relates to a passenger car safety device intended to protect the occupants of the passenger, including the driver in the passenger car, in the event of a frontal impact of the passenger car in another vehicle or stationary object and the subsequent impact of a crush on the front of the passenger car. car.

BACKGROUND OF THE INVENTION

There are various solutions for protecting passengers, especially those in the front seats of a vehicle.

For example, Publication DE10356946 A1 discloses a car seat shaped like a single shell with a lined front surface. The seat is mounted axially-movably on a guide rail fixed to the floor of the car. In the event of an impact, the driver or passenger rotates slightly about an axis in the pelvis area and his head, which due to the impact should move forward, actually moves in such a way that it avoids impact in the front frame of the passenger car roof.

This solution does not provide reliable protection for all occupants of the car in the event of a severe frontal impact, which results in crushing of the front of the passenger car.

Publication DE19938938 A1 discloses a vehicle occupant restraint system which, upon a frontal impact of the car, reduces the acceleration applied to the passenger.

This system includes a seat fitted with a seat belt that is mounted on the floor of the car with the ability to move in the direction of the force exerted when the car is crushed by the impact. A car crash detector is also provided. The seat base is mounted on guide rails, with the possibility of moving them at a certain distance in the longitudinal

-2 Direction of the car. To move the seat in a direction opposite to the direction of travel of the car, a first actuator of the piston-cylinder type actuated by a gas generator is provided. The first propulsion accelerates the seat to the floor of the car in the same direction as the impact force. A second actuator similar to the first is intended to accelerate the seat relative to the floor of the car in a direction opposite to the direction of the impact force.

This safety system is too expensive and complex to protect all passengers in a car.

SUMMARY OF THE INVENTION

The problem to be solved by the present invention is to provide a passenger car safety device which is of a simple and inexpensive design that allows protection against injury to passengers, including the driver, both front and rear. the back seat, in the case of a frontal impact of a car and the resultant impact of a car crushing.

The problem was solved by a passenger car safety device in the frontal impact of the car, including seats fitted with seat belts, with the front seats fitted with the possibility of adjustable longitudinal movement of the car. According to the invention, all seats are mounted on a platform which is fixed in its front part with rods, which in turn are fixed to the bumper of the car. The platform is mounted on the floor of the car with the possibility of longitudinal movement in the direction of the impact force at a distance equal to the specified distance provided between the rear seat and the trunk of the car.

Preferably, the longitudinal movement of the platform on the floor of the car is secured by rollers bearing to

platform and guided in guide rails fixed to the floor of the car.

Also, in a preferred embodiment, the platform consists of a U-shaped metal base and a support frame formed by longitudinal and transverse reinforcing beams.

An advantage of the safety device according to the invention is its simplified and inexpensive design, which allows the occupants of both the front and rear seats to be prevented from injuring the frontal impact of a light car and the resulting crushing of the car.

Another advantage is that the structure of the safety device can be easily fitted and fitted to existing cars.

EXPLANATIONS OF THE FIGURES Attached

The invention is illustrated by way of an exemplary embodiment with reference to the accompanying drawings, in which:

Figure 1 is a schematic top view of a safety device according to the invention,

2 is a schematic bottom view of the platform of FIG. 1,

EXAMPLES FOR THE IMPLEMENTATION OF THE INVENTION

The passenger car safety device shown schematically in the accompanying drawings consists of a platform 1 composed of a U-shaped metal base 2. On the underside of the base 2 is provided a reinforcing frame made up of fixed, fixed, in this example welded, longitudinal 3 and transverse 4 reinforcing beams.

To the platform 1 are mounted rollers 5, guided in rails 6, which are located in the longitudinal direction of the car and are fixed to the floor 7 of the car.

Front seats 8 and rear seats or seat 9 are mounted in a known manner on the base 2 of the platform 1.

-4 As is known, they are mounted on rails (not shown in the figures), with the possibility of adjusting their position in the longitudinal direction.

A certain distance is provided between the rear seat (or seats) 9 and the car boot (not shown in the figures) which determines the maximum running of the platform 1 on the rails 6.

The platform 1 is fixed in its front part with two rods 10, which in turn are fixed to the bumper 11 of the car.

APPLICATION OF THE INVENTION

In the case of a frontal impact of a car in another vehicle or in a stationary object and subsequent crushing of the bumper 11 or the front of the car, the platform 1, together with the seats 8 and 9 and the passengers on them, is pushed through the rods 10 and moved in the direction of the force of impact, ie to the trunk of the car. This protects the passenger car from serious and life-threatening injuries.
