JPH11245843A - Car body skeleton and human body protecting device for moderating impact in automobile at collision - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce severe injury of an occupant at collision by fixing a gate-type H-shaped steel column to an S-shaped large H-shaped steel linking front and rear wheels of the both side surfaces and by doubly providing impact moderating device on the front surface part of a car body skeleton which is connected with the upper part through a round steel. SOLUTION: For a car body skeleton, a large H-shaped steel 2 having the S-shape along the upper part of the front and rear wheels 1 of the both side surfaces forms a main skelton, and a column of gate-type H-shaped steel 3 is welded between front and rear doors. A thick round steel 4 is through-welded into the gate-type H-shape 3, is inserted into the large H-shaped steel 2 through a hardware 8 and fastened with nuts, and the thick round steel is bending-welded with a thin round steel 7. An S-shaped bundled plate spring 9A as an impact moderating device is fixed to a top flange surface of the front surface part of the large H-shaped steel 2, and thin steels 12 of a first-layer protecting frame are hinged with the upper and lower parts of the bundled plate spring 9A through a spring 10. Angle steels 13 of a second-layer protecting frame are screwed with the upper and lower parts of the thin steels 12 through a plate spring. Thus safety can be sufficiently kept at not only head-on collision but also side impact.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body skeleton and a protective device for mitigating a serious obstacle for an occupant in an automobile at the time of a collision.

[0002]

2. Description of the Related Art A conventional vehicle body skeleton is designed to have a structure designed so that, when an impact is received during a frontal collision, the front body shrinks and collapses to mitigate the impact and prevent a direct hit inside the vehicle. . However, in the event of a serious impact, even when wearing a seatbelt, there were problems such as engine peripherals breaking the partition plate and hitting the feet directly, or hitting the interior with hard interior materials and equipment. Therefore, there is a known air bag for the purpose of protecting the body.

[0003]

In the prior art automobile, the weight of the entire vehicle is emphasized for fuel efficiency and economy, and the riding type body frame is assembled by pressing an extremely thin steel plate. However, there was a problem with the safety in the event of a collision.

[0004] It is an object of the present invention to provide a vehicle body skeleton that solves the above-mentioned problems, and a device for protecting a human body in a room.

[0005]

In order to achieve the above object, a shock absorbing body frame according to the present invention comprises: a large H-shaped steel bent and formed in an S shape so as to straddle the front and rear wheels on both sides; Welded H-shaped steel columns formed into a gate shape from the center of this H-shaped steel, and made a body frame composed by connecting the upper part with round steel, and the flange of the vertical part of the tip of the large H-shaped steel A strong spring and a leaf spring are provided on the surface, and the front part is provided in a double manner. Incidentally, the large H-shaped steel in the present invention has the largest size in consideration of the breaking strength, economy, or indoor space.

[0006] A part of the upper part of the handle is made of a thick and resilient material, and a very soft and resilient padding is put on the handle, and a donut-shaped bag-shaped protective device is attached and detached. It is characterized by being freely pivoted.

In addition, a plate-like protection device in which glass or the like is lined with thick transparent vinyl reinforced with ultra-high tension wire is screwed to the ceiling and the front panel in front of the driver's seat and the passenger's seat. I do.

In addition, a protection device formed of a very soft and resilient padding in the form of a table is provided in front of the front passenger seat and the rear seat.
The front seat is characterized by being guided up and down and stopped by a guide.

Further, a transparent vinyl-coated wire is detachably pivoted at a position inside the door glass as far as possible from the glass surface at an interval which does not hinder the protection of the side surface, or can be pulled horizontally by an upper and lower guide. A grid-like protection device is provided. If you are worried about being submerged, attach a floating hatch to the roof above the front and rear seats so that you can escape in an emergency.

[0010]

Embodiments of the present invention will be described with reference to the drawings. 1 and 2, 1 is a wheel, 2
Is a large H-beam of the main body frame formed in an S-shape along the front and rear wheels on both sides, and the four corners seen from above are slightly bent inward so as not to be angular, and the bent portion 6 The web is thicker than the other webs. Numeral 3 denotes an H-shaped steel column formed in a gate shape between the front and rear doors 28 and welded to the large H-shaped steel 2. Reference numeral 4 denotes a thick round steel having a gate-shaped H-section steel connected at its head. The mounting method is to make a hole in the H-section steel 3 by through-peel welding. And tighten the nut. Numeral 5 indicates bending welding to the thick round steel 4, and numeral 7 indicates a thin round steel. In addition, the strength of the steel material of the body frame is improved by using high-tensile steel. If the workability can be overcome, the cross section may be not an open cross section of the H-section steel but a square cross section of a closed cross section having good cross section performance, and the material may not be a steel material.

In FIG. 3, a bundle leaf spring 9A in which thin leaf springs are bundled is provided on the flange surface at the front end of the large H-section steel 2.
