Abstract

PURPOSE:To prevent formation of a sharp edge due to crack of a spoke finisher etc. when a shock load is applied, by forming a flexible part along a spoke core- metal on the spoke finisher. CONSTITUTION:A spoke finisher 1 is constituted of the first thin hinge 11 over the edge part 1b installed onto a stay 3, the second thin hinge 12 in the lower part close to a grip part 6 from a center part 1a at the edge part 1c engaged with the grip part 6, and the third thin hinge 13 in the lower part in the vicinity of the bent part 2b of a spoke core-metal 2 between the first thin hinge 11 and the center part 1a. A flexible part 10 in which the spoke finisher 10 can be made flexible along the core-metal 2 is constituted of these first-third thin hinges 11- 13 described in the above.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steering wheel for an automobile, and particularly to a steering wheel whose spoke finishers are made of synthetic resin.

Examples of conventional steering wheels include those shown in FIGS. 1 and 2. In order to reduce costs and reduce heavy loads, the spoke part S consists of a spoke finisher l made of synthetic resin, a spoke core metal 2 such as an iron rod arranged on the nest side, and a body cover 3 that covers the core metal λtS. The spoke finisher 1 is fixed to the body cover 3 through a bracket 2a integrated with a core metal 2 at its center part /a with screws 7, and at its end part /b on the side of the boss part B.
In order to improve the appearance, YF is added to the inside of the Horn Bud J.
, [and screws are attached to the pillar 3a that protrudes from the body cover 3! is fixed. Also, the spoke core metal 2 is bent 2b, 2 inside the boss part B to make the spoke part sl look thinner.
The end part /c of the spoke finisher 1 is engaged with the concave part 6a of the grip part B of the rim R.

However, in such a conventional steering wheel, the gap 9 between the spoke finisher l and the spoke core metal 2 is set small, and the spoke finisher l is fixed at two ends /b and /c. Also, grip 1llQ4 of spoke finisher 1
Since part/c was simply inserted into the recess 6a of the grip O, the rim R of the steering wheel
When an impact is applied from the direction of arrow F, the spoke, T5 gold 2
If the spoke finisher I exceeds the limit of distance as shown in Fig. 43, it will crack at the position indicated by the symbol and a sharp edge will be formed. Also, the 4th part lc of the grip 61 rule rises and a sharp edge is formed there. There was a problem in that there was a risk that the rider would collide with this sharp edge and be injured.

This invention has been made in view of these conventional problems, and is made by forming a bendable part in the spoke finisher so as to form a bending opening along the spoke core metal. The purpose is to settle the issue once and for all.

Hereinafter, this invention will be explained based on the drawings.

FIG. q is a diagram showing an embodiment of the present invention.

, @ When the members are the same as or the same as those shown in Figs.

First, to explain the configuration, IO is a bendable part formed on the spoke finisher and screwed onto the support column 3b. Spoke finisher 7 is attached to the end /b of the side attached with
In addition, on the side that is engaged with the concave portion 6 of the grill lug portion 6, there is a second thin hinge t in the F portion closer to the grill lug portion 6 than the center portion /a. Additionally, a third thin hinge 13 is formed at the F portion near the bent portion 2b of the spoke core 2 between the first thin hinge // and the central portion la.

I'll explain how it works in a vague way.

If the spoke core metal 2 is deformed due to a strike from somewhere in the arrow F direction of the steering wheel rim RKiJj diagram, the first thin hinge // and the 34th thin hinge 13 of the bendable portion 10 of the spoke finisher l Since the spoke core metal 2 changes according to the deformation of the spoke core metal 2, it is possible to prevent cracks from occurring due to deformation that exceeds the limit of the groaning of the synthetic resin, and a safe steering wheel without sharp edges can be obtained. In addition, since the resin hinges are made with bendable tM10 //, /J,
Due to internal protrusion countermeasures f and lA-shaped chivalry, the spoke finisher remains the same even if the depth of the spoke changes? Since the second thin hinge t is also provided on the 4th part /c on the Grisoge 6 side, it is possible to use it.
l@L, Grits 6's 4th part inserted into A/c
This prevents the surface from floating and causing sharp edges.

As explained above, if this invention is used (D), the impact on the rim of the steering wheel will be
Even if the spoke finisher is printed, sharp edges can be prevented from occurring due to printing on the spoke finisher, and the same spoke finisher can be used once for both shallow and deep spokes.

Claims (1)

[Claims] In a steering wheel consisting of a spoke finisher whose spoke parts are made of synthetic resin, a spoke core metal arranged on the back side of the spoke finisher, and a body cover that supports the core metal, the steering wheel can be bent in accordance with the bending of the core metal. The steering wheel has a unique feature in that it is formed into a freely bendable spoke finisher.
