DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention comprises a bumper facia having a substantially horizontal U-shaped cross section, and a reinforcement supporting the bumper facia also having a substantially horizontal U-shaped cross section,
The present invention relates to a bumper in which a sight shield is disposed on the vehicle body side to hide an upper gap formed between the bumper and the vehicle body when the bumper is attached to the vehicle body.

"Prior Art" As shown in FIG. 1, a bumper 20 is attached to the front (or rear) of a car body 10 via a bumper stay 21.
is attached to the vehicle body, the bumper 20 and the vehicle body 10
Some vehicles have a sight shield 11 fixedly disposed on the vehicle body 10 to hide the gap formed between the vehicle body 10 and the vehicle body 10.

As a conventional bumper 20, there is one shown in FIG. 2, for example.

That is, the bumper 20 is a bumper facia 30.
and Rainforce 40.

The bumper facia 30 is made of a flexible synthetic resin material such as urethane, and includes a tip surface portion 31 that most protrudes outward from the vehicle body 10, and an upper surface portion 32 and a lower surface portion that extend from the upper and lower ends of the tip surface portion 31 toward the vehicle body 10 side. 33, and is formed into a substantially horizontal U-shaped cross section.

Rain force 40 is bumper force Asia 30
The top surface portion 4 corresponds to the tip surface portion 31 of the
1, an upper surface receiving portion 42 extending from the upper and lower ends of the top surface portion 41 toward the vehicle body 10 side, and receiving the upper surface portion 32 of the bumper face portion 30, and a lower surface receiving portion 43 receiving the lower surface portion 33. U
It is formed in a letter-shaped cross section.

A clip portion 34 is provided to protrude inward from the tip surface portion 31 of the bumper faceia 30.
An engaging claw 35 is provided at the tip of the clip part 40, and the tip of the clip part 34 is inserted into a locking hole 44 bored in the top surface 41 of the reinforcement 40, and the engaging claw 35 is inserted inward. Although it is movable, it is locked in a locking hole 44 so that it cannot come off.

An engagement groove portion 45 is formed at the end portion of the upper surface receiving portion 42 of the rain force 40, and an engagement groove portion 45 is formed in the end portion 36 of the upper surface portion 32 of the bumper faceia 30.
Similarly, an engagement groove portion 46 is formed at the end portion of the lower surface receiving portion 43, and the end portion 37 of the lower surface portion 33 of the bumper faceia 30 is fitted into the engagement groove portion 46.

Engagement grooves 45 and 46 forming the ends of the reinforcement 40 on the vehicle body 10 side are arranged along the vehicle body 10 through gaps a and b so as not to adversely affect the vehicle body 10 when the reinforcement 40 is deformed in a light collision. Since the upper gap a deteriorates the appearance quality of the automobile if left as it is, a sight shield 11 is provided to hide the gap a.

The sight shield 11 is fixed to the vehicle body 10 with one side serving as a mounting piece 12, and the other side serving as a concealing piece 13 that covers the gap a and overlaps above the terminal portion 36 and the engagement groove portion 45.

When colliding with the tip end surface 31 of the bumper fascia 30, the bumper fascia 3
0 is deformed, and if the collision is a light one, the collision energy is absorbed. (Refer to Japanese Utility Model Application Publication No. 57-100554) However, in such a conventional bumper 20, when the bumper facia 30 deforms, the upper surface portion 32 of the bumper facia 30 deforms immediately from the terminal portion 36. Therefore, the tip of the concealing piece 13 of the sight shield 11 cannot be set in a sufficiently extended state, and the engaging groove portion 45 and the terminal portion 36 cannot be sufficiently hidden, resulting in poor appearance and insufficient appearance quality. The problem was that it was not possible to obtain

``Object of the Invention'' The present invention has been made by paying attention to such conventional problems, and solves the above problems by making it possible to sufficiently hide the unsightly portion of the bumper 20 with the sight shield 11. The aim is to provide a bumper that solves this problem.

"Structure of the Invention" In order to achieve the above object, the present invention provides a bumper faceia having a substantially horizontal U-shaped cross section;
In the bumper, which is made up of a reinforcement that also has a substantially horizontal U-shaped cross section and supports the bumper fascia, and in which a sight shield is disposed above to hide a gap between the bumper face and the vehicle body, an end portion of the reinforcement is provided with a reinforcement in the direction of travel. forming an engaging groove portion that opens to gradually expand in the direction, and providing a vertical rib having a wedge-shaped fitting piece portion extending in the distal direction at the end portion of the bumper faceia, and engaging the vertical rib of the bumper faceia; A bumper characterized in that a mating piece is fitted into an engagement groove of the rain force, and a tip of a concealing piece of a sight shield disposed above the bumper extends beyond the engagement groove of the rain force. That is.

The wedge-shaped fitting piece of the vertical rib at the end of the bumper faceia fits tightly into the engagement groove of the reinforcement without wobbling, and prevents the end of the bumper faceia from rotating in the event of a collision, etc. The folded line is held far in front of the engagement groove of the rain force, making it difficult to interfere with the concealing piece of the sight shield.

Therefore, the concealing piece of the sight shield can be sufficiently extended by that amount, so that the gap between the bumper and the vehicle body is sufficiently concealed and the appearance quality is improved.

“Embodiment” An embodiment of the present invention will be described below based on the drawings. Note that the same parts as in the conventional example are given the same reference numerals and redundant explanations will be omitted.

FIG. 3 shows an embodiment of the present invention, in which the engagement groove 45 of the reinforcement 40 is connected to the terminal surface 45a.
and the guide flange 4 bent back from the terminal surface portion 45a.
5b, the wedge-shaped vertical rib 38 is formed with an opening that gradually expands in the direction of travel, fits into the engagement groove 45, and extends in the distal direction from the distal end 36a of the terminal section 36. 36, the vertical rib 38 is made up of a fitting piece part 38a that abuts and fits on the guide flange 45b, and a reinforcing piece part 38b extending from the fitting piece part 38a toward the distal end side.
8 are arranged in a row in the lateral direction along the vehicle body 10.
End 36a of upper surface portion 32 of bumper facia 30
is spaced apart from the terminal surface portion 45a of the upper surface receiving portion 42 of the reinforcement 40.

On the other hand, the concealment piece 13 of the sight shield 11 is further extended from the position where it overlaps the engagement groove part 45,
The tip portion 14 covers the reinforcing piece portion 38b of the vertical rib 38.

In the bumper 20 having the above configuration, when an impact is applied to the tip end surface 31 of the bumper fascia 30 due to a collision, the engaging claw 35 of the clip section 34 will move inward with respect to the locking hole 44 of the top surface 41 of the reinforcement 40. Since it can be moved to
Since the terminal portions 37 of No. 3 are restricted from being displaced toward the vehicle body by the engagement groove portions 45 and 46 of the reinforcement 40, the upper surface portion 32 and the lower surface portion 33 are bent, and the bumper face 30 is aligned with the imaginary line in Figure 3. Transform as shown.

In the vicinity of the end portion 36 of the upper surface portion 32, the wedge-shaped fitting piece portion 38b of the vertical rib 38 fits tightly into the engagement groove portion 45 of the reinforcement 40 without wobbling, and is held rigidly so as not to rotate. , if the vertical rib 38 breaks, the reinforcing piece 3 of the vertical rib 38
The tip 1 of the concealing piece 13 of the sight shield 11 is bent based on the bending line at the tip of the sight shield 11.
There is no interference with 4.

It goes without saying that the end portion 37 of the lower surface portion 33 of the bumper face 30 may also be provided with a vertical rib.

"Effects of the Invention" According to the bumper of the present invention, the concealing piece of the mounting piece sufficiently covers and conceals the terminal part of the bumper facia and the vicinity of the engagement groove part of the reinforcement.
Unsightly parts are not visible, the appearance is good, and the appearance quality of the automobile can be improved. In addition, as a result of providing the vertical ribs, the end part fits securely into the engagement groove, so there is no rattling and noise, and since it is reinforced by the engagement groove, the vicinity of the end part is less likely to be damaged. This also has the advantage of increasing the ability to absorb collision energy.
