Abstract

The utility model relates to an inverse buffering safety seat which is a novel seat used for preventing passengers from suffering injury and death caused by the inertia forward momentum of the passengers during the urgent stop of a vehicle. The seat is inversely installed on a chassis of the vehicle, and comprises a buffering pad, a sliding sleeve, a sliding rail, springs, a limitation sleeve, a base, etc. According to the characteristics that the sliding seat can slide along the sliding rail and the buffering pad and the springs have buffering functions, the inertia forward momentum generated by human bodies is converted into the pressure from the backsides of the human bodies to the buffering pads and the springs during the urgent stop of the vehicle; thus, the passengers can not suffer the injury and depth caused by cases that the passengers are disengaged from the seat to clash forwards during the urgent stop of the vehicle.

Description

Reversal direction buffer safety seat

The utility model relates to and a kind ofly prevents that in the anxious stopping time of vehicle the occupant from the reverse baffle safety seat of injures and deaths taking place because of the inertia forward momentum.

At present, known seat is that forward is installed in vehicle chassis, and when the anxious stopping time of vehicle, the inertia forward momentum that human body produces makes occupant's clear off the seat crash, cause easily injures and deaths forward.

The purpose of this utility model provides a kind of reverse baffle safety seat that can protect passenger's safety when the anxious stopping time of vehicle effectively.

The purpose of this utility model is to realize like this; At first be that reverse baffle safety seat oppositely is installed in vehicle chassis, oppositely the baffle safety seat is made up of cushion rubber, sliding seat, sliding sleeve, slide rail, spring, stop collar, base; Cushion rubber is fixed on the sliding seat, and sliding seat contacts with the slide rail of base by sliding sleeve, between the stop collar on sliding sleeve and the slide rail spring is housed.Its principle of work is can absorb the inertia forward momentum that produces because of the anxious stopping time human body of vehicle according to reverse baffle safety seat, and slows down this inertia forward momentum by cushion rubber, spring.After the inertia forward momentum of anxious stopping time of vehicle, human body generation at first acts on cushion rubber, cushion rubber pressurized, force transmission is arrived sliding seat, sliding seat just slides and is pressed on the spring along the slide rail on the base, because spring has buffer action, the inertia forward momentum that the anxious stopping time human body of vehicle is produced reduces to the degree that human body can bear.

Owing to adopt such scheme, make the occupant cause injures and deaths anxious unlikely the crashing forward of stopping time of vehicle, the structure of seat adopts ordinary buffer material, slide mechanism, spring, simple in structure.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structure principle chart of the present utility model.

Among the figure 1, cushion rubber 2, sliding seat 3, sliding sleeve, 4, slide rail 5, spring 6, stop collar 7, base

In Fig. 1, cushion rubber (1) is fixed on the sliding seat (2), sliding seat (2) by on sliding sleeve (3) contact slide rail (4), the slide rail (4) stop collar (6) is housed, between sliding sleeve (3) and stop collar (6), spring (5) is housed, slide rail (4) is fixed on the base (7).When the anxious stopping time of vehicle, the inertia forward momentum that human body produces at first acts on cushion rubber (1), behind cushion rubber (1) pressurized force transmission is arrived sliding seat (2), sliding seat (2) just slides along slide rail (4) by sliding sleeve (3) and is pressed on the spring (5), because stop collar (6) is housed on slide rail (4), when spring (5) pressurized arrives the limit, just application force is delivered to base (7) by stop collar (6), for guaranteeing that base (7) does not break away from the chassis in the effect that is subjected to the inertia forward momentum that human body produces because of the anxious stopping time of vehicle, should strengthen base (7) and chassis bonded assembly intensity.Simultaneously, for making cushion rubber (1) performance buffer action, it is concordant substantially with occupant's the crown that cushion rubber (1) is fixed on the height of backrest, backrest of sliding seat (2), and the height of cushion rubber (1) is concordant with the height of backrest.

Claims

1, the reverse baffle safety seat that constitutes by cushion rubber, slide mechanism, spring, it is characterized in that: cushion rubber (1) is fixed on sliding seat (2), sliding seat (2) contacts with slide rail (4) by sliding sleeve (3), stop collar (6) is housed on the slide rail (4), between sliding sleeve (3) and stop collar (6) spring (5) is housed, slide rail (4) is fixed on base (7).

2, reverse baffle safety seat according to claim 1, it is characterized in that: cushion rubber (1) is fixed on the backrest of sliding seat (2), and the height of backrest is concordant substantially with occupant's the crown, and the height of cushion rubber (1) is concordant with the height of backrest.
