【考案の詳細な説明】
本考案は自動車用バンズの取付部構造に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a mounting structure for automobile vans.
自動車において、衝突事故時の安全対策としてフレーム
を該ル−ムの長手方向に所定以上の荷重が作用したとき
座屈変形し得るよう構成し衝突時の衝撃荷重がバンズ及
び該バンズ取付用のステーを介してフレームに作用する
とフレームがつぶれ、衝撃エネルギーを吸収するように
したものが既に開発されている。In automobiles, as a safety measure in the event of a collision, the frame is constructed so that it can buckle when a predetermined load or more is applied in the longitudinal direction of the room. A system has already been developed in which the frame collapses when it acts on the frame through the shock absorber, absorbing the impact energy.
このような衝撃吸収式の車体構造のものにおいて、バン
ズは通常該バンパに固定されたステーをフレームに前後
２ケ所ボルト締めにて取付固定されるのが普通であり、
そのためにフレームの上記ステー取付用の２本のボルト

形不能であり、フレームはバンズに対し奥の方の取付ボ
ルトより先からつぶれることになり、結局該２本の取付
ボルト間の距離分だけクラッシュストロークが小となっ
てしまうという問題がある。In such shock-absorbing car body structures, the vans are usually fixed to the frame by bolting the stays fixed to the bumpers in two places, front and rear.
For this reason, the space between the two bolts for attaching the stay to the frame is stretched between the stay and the bolt, making it impossible to buckle and deform, and the frame collapses from beyond the mounting bolt at the back of the vans. As a result, there is a problem in that the crush stroke ends up becoming smaller by the distance between the two mounting bolts.
本考案は上記のよ′ンな問題に対処することを目的とす
るものであり、以下附図実施例につき説明する。The present invention is aimed at addressing the above-mentioned problems, and will be described below with reference to the accompanying drawings.
第１図において、１はバンズ、２は該バンズ１に固着さ

レーム３に前後２ヶ所Ａ、Ｂにおいてボルト締めするこ
とにより取付支持される。In FIG. 1, 1 is a bun, 2 is a stay fixed to the bun 1, and 3 is a frame. The bun 1 is mounted and supported by bolting the stay 2 to the frame 3 at two locations A and B in the front and back. .
ステー２及びフレーム３には上記Ａ、Ｂの２ケ所におい
て取付用ボルト孔２ａ、２ｂ及び３ａ。The stay 2 and frame 3 have mounting bolt holes 2a, 2b and 3a at the two locations A and B mentioned above.
３ｂが設けられ、フレーム３のポル）孔３ａ、３ｂの内
側に溶接等により固着されたナツト５ａ、５ｂにボノン
ト孔２ａ、２ｂＹ貫通した取付ポル） ４ａ。3b is provided, and a mounting hole 4a passes through the Bonont hole 2a, 2bY through the nut 5a, 5b, which is fixed by welding or the like to the inside of the hole 3a, 3b of the frame 3.
４ｂをそれぞれ螺着してステー２をフレーム３に９付け
るが、本考案ではステー２のバンズ１に対シ奥側ノホル
） 孔２ ｂに、バンズ１側のボルト孔２ａ力向に向け
て所定長さｔの長孔２ｃを形成した構造とする。4b are respectively screwed to attach the stay 2 to the frame 3. However, in the present invention, the bolt hole 2b on the bund 1 side of the stay 2 is inserted into the bolt hole 2a on the bund 1 side in a predetermined direction in the direction of force. It has a structure in which a long hole 2c of length t is formed.
該長孔２ｃは図示のようにその幅がボルト孔２ｂに挿通
されるべき取付ボルト４ｂの径よりやや狭い形状として
おく。As shown in the figure, the elongated hole 2c has a width slightly narrower than the diameter of the mounting bolt 4b to be inserted into the bolt hole 2b.

相当する範囲のクラッシュストロークの増加分と取付ポ
ル）４ｂによる長孔２ｃの押し広げによる抵抗弁とによ
り衝突エネルギーの吸収量は大幅に増大する。In the above configuration, when an impact load P acts on the buns 1 during a collision, the load P is transmitted to the frame 3 via the stay 2 and the frame 3 buckles, but at that time the bolts 4b on the back side Since the frame 3 is movable relative to the stay 2 while expanding the elongated hole 2c, the frame 3 is buckled and deformed from the part fixed by the mounting bolts 4a on the bumper side, as shown in FIG. has moved to the end of the elongated hole 2c, and due to the increase in the crush stroke in the range corresponding to the length t of the elongated hole 2c of the frame 3 and the resistance valve due to the expansion of the elongated hole 2c by the mounting pole 4b. The amount of collision energy absorbed increases significantly.
このようにして本考案によればバンパステーの奥側の取

小型車等における衝突エネルギー吸収構造として実用上
多大の効果をおさめ得るものである。In this way, according to the present invention, the crash stroke of the frame can be lengthened by an extremely simple configuration in which a long hole with a width narrower than the diameter of the bumper side mounting bolt is formed in the mounting bolt hole on the back side of the bumper stay. The length of the hole can be increased by the length t, and the amount of collision energy absorbed can be greatly increased by plastic deformation of the long hole by the mounting bolt.In particular, the length of the frame from the fuel tank mounting part to the rear end can be increased significantly. This structure can have a great practical effect as a collision energy absorbing structure for small cars and the like where the height cannot be increased very much.
