Description

VEHICLE REDUCTION

The invention relates to the field of transport engineering, namely, to the design of the rear seats of the vehicle.

A known design of the rear seat of the vehicle when unfolding which forms the cargo area (prototype - see AS USSR 1393678 B60N I / OS- 1/04).

The seat contains a backrest, which is hinged at the edges below to the cushion, which, in turn, is pivotally connected to the body in its front part. The upper part of the back is kept from locks by locks.

For the formation of a cargo platform in the specified seat, the back locks open, after which it is laid on the pillow, while the hook of the movable link of the swivel mount disengages from the latch. After that, the seat leans forward relative to the hinges of the pillow.

A drawback of the known technical solution lies in the flakiness of the design of fasteners, which leads to an increase in material consumption and the complexity of their manufacture.

The objective of the proposed solution is aimed at simplifying the design of the mechanisms of fixation and fastening of the backrest of the rear seat of transport information.

To solve this problem, the design of the rear seat is proposed. The fastening and fixing mechanisms of which have a simplified shape, which makes it easy to remove and fix the back in the working position.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation on the priority date in the main and related sections shows that the totality of the essential features of the claimed solution was not known, therefore, it meets the patentability condition of novelty.

Analysis of known technical solutions in the art showed that the proposed device has signs.

MM 5: B 60 N 2/10

which are absent in the known technical solutions, and their use in the claimed combination of features makes it possible to obtain a new technical effect, therefore, the proposed technical solution has an inventive level in comparison with the current level of technology.

The premiere technical solution is industrially applicable, since it can be manufactured industrially, efficiently, feasibly and reproducibly, therefore, industrial applicability meets the patentability condition.

The softness of the proposed solution is illustrated by drawings:

FIG. 1 is a side view of the rear seat in the operating position.

FIG. S is a general view of the rotary sleeve.

FIG. 3 is a side view of FIG. 2.

ZhG. 4 is a general view of a stationary sleeve.

FIG. 5 is a side view of FIG. 4.

FIG. 6 is a side view of the rear seat in the load position.

The seat (1) contains a cushion (2) and a backrest (3), when unfolded which a cargo box forms.

The backrest (3) of the seat (1) in the working position is set by the lower latches (4) in the open groove (5) of the fixed bushings (6), mounted on the sidewall (7) of the body.

in the upper part of the backrest (3) it is kept from rotation by locks (8) j which are engaged with the clamps (9) installed on the side surface of the backrest (3).

The lock (8) is mounted on the sidewall (i-box and is a rotary eccentric sleeve that holds the plastic sleeve (10), the lever (11), the clip (-12), ... t / spring washer (13 ), groove (14).

To set the backrest (3) in the working position, the clamps (4) are installed in the grooves (5) of the fixed bushings (6), after which the backrest (3) rotates around the geometric center of the fixed bushings and engages with the clamps (9) with

grooves (14) of the rotary bushings. By turning the lever (11), the latches (9) are closed in the groove (14) of the rotary bushings, and the back is rigidly fixed at an angle between the axis

- the symmetry of the groove (14) of the sleeve (10) and the horizontal axis of the sleeve (6) is greater than 90.

To install the backrest (3) in the loaded position, it is necessary to turn the lever (11) of the rotary sleeve (10) until the direction of the groove axis (14) of the rotary sleeve coincides with the path of the upper latches (9) when the backrest is relative to the lower latches (4) installed in fixed bushings (6). After that, the backrest (3) disengages from the latches (4) and (9) with the bushings (6) and (10) - and is installed in the load position.
