Absorbs impact energy device for the safe transportation of people MAINLY road passenger transport

摘要

The utility model is a part of the automotive unit and comprises (in its first embodiment) one pair or several pairs of seats (1 and 2) equipped with security belts (6), means (3) seat connection (1 and 2) with the frame (4) vehicle for driving them in motion along a predetermined path during longitudinal impact by the vehicle body, and means (5) for absorbing impact energy. Means (3) adapted to ensure movement in opposite directions of each seat (1 and 2) of the pair. Means (3) consists of two symmetrical arrangements, each of which includes the same length two base link (9 and 10) and associated hinge (11) between themselves and the joints (12 and 13) with sliders (14 and 15) placed in the guide (17 and 18) of the frame (4), the middle base units (9 and 10) are connected by hinges (19 and 20) with two associated hinge (21) together to form a diamond shaped units (22 and 23). Means (5) is in the form of two tension springs (24 and 25) placed in parallel planes and axes associated with one diagonal of the rhombus. There are modifications: one symmetrical mechanism means (3) connected with their romboobrazuyuschimi functioning common hinge to the frame (4) and one of the basic units - with a guide in the form of slots in the frame (4), the seats are arranged at different distances from and base units rotational center means (5) is made of three tension springs; or each symmetrical mechanism means (3) basic axis of the hinge connection units suspended on a rack (4), and means (5) is represented by the general romboobrazuyuschimi functioning as a hydraulic cylinder, the unlike Rod and piston chamber which are connected hoses. According to the second embodiment of its means (3) adapted to ensure movement in opposite directions of each of the two rows of seats and is represented by two platforms mounted in longitudinal guides of the frame (4), means (5) is in the form of two hydraulic cylinders, each of which is pivotally connected its cylinder to the frame (4) and a rod - on the one of the platforms, the same name rod and piston cavity coupled hoses. Provides significant impact absorption energy absorption by mutual impact pulse due to the oncoming traffic, the masses of human bodies and seats. 2 bp 4 and ZP f ly-7-yl.
