Japanese Utility Model Sho 62-54830

The armrest for a vehicle is required to have tactile feel, that is, flexibility when lightly touched, and a load holding ability to support an occupant's elbow, but in the armrest of Patent Document 1, these two requirements are met by selecting a cushioning material. I have to be satisfied.
If the cushion material is made flexible (if the elastic repulsive force of the cushion material is weakened), although the feel can be improved, the load holding ability is lowered, and the occupant sinks largely when a load is applied to the elbow. . Conversely, if the cushioning material is stiffened (if the elastic repulsive force of the cushioning material is strengthened), the load holding ability will be high, and even if the occupant places a load on the elbow, the sinking can be suppressed. , The touch sensitivity will be deteriorated.

  In order to solve the above problems, according to the present invention, an armrest core material elongated in the longitudinal direction of the vehicle and having a storage space, a cushion material stored in the storage space of the armrest core material, and the cushion material are covered. In the vehicle armrest provided with the skin attached to the armrest core material, the cushioning material is characterized by having a recess on the lower surface thereof.

  According to the above configuration, when the occupant places the elbow, the cushion material bears a load in the area excluding the recess until the depression of the recess of the cushion material is crushed so that the elastic repulsive force is weak. When a larger load is applied and the sinking exceeds a predetermined amount, the recess is crushed and the cushion material bears the load over the entire area, so that the elastic repulsive force becomes strong. Therefore, if the cushioning material is selected such that sufficient elastic repulsive force can be obtained in a state where the sinking exceeds a predetermined amount, the sinking can be suppressed and also the tactile sensation can be improved.

Preferably, the recess is formed in an area excluding the peripheral portion of the cushion material.
According to the above configuration, the cushion material can be stably elastically deformed until the depression sinks by a predetermined amount until the recess is crushed.

Preferably, the armrest core material has a fitting hole, and the cushion material has a fitting protrusion to be fitted into the fitting hole.
According to the above configuration, the shift of the cushioning material accommodated in the accommodation space of the armrest core material can be suppressed without using an adhesive.

Preferably, the armrest core material is a bottom wall elongated in the longitudinal direction of the vehicle, an outer wall formed on the outer side of a compartment of the bottom wall, a front wall formed on the front side of the bottom wall and connected to the outer wall, The rear wall formed on the rear side of the bottom wall and connected to the outer wall, the housing space is open at the upper side and the vehicle compartment side, and the fitting hole is formed at the intersection of the bottom wall and the front wall It includes a formed front fitting hole, a rear fitting hole formed at the intersection of the bottom wall and the rear wall, and an outer fitting hole formed at the intersection of the bottom wall and the outer wall. .
According to the above configuration, since the cushioning material is supported at the front end, the rear end, and the outer side by the fitting portion and the fitting hole, the cushion material can be stably supported.

  Preferably, a brittle fracture line is set in the armrest core material, which extends in the longitudinal direction of the vehicle and promotes a brittle fracture when a load in the vehicle width direction acts, and a plurality of lightening holes aligned on the brittle fracture line A part is provided as the above-mentioned fitting hole.

  According to the present invention, it is possible to enhance the feel of the armrest and prevent the sinking at the time of load application.

It is a perspective view showing the armrest for vehicles concerning one embodiment of the present invention. It is a disassembled perspective view of the armrest core material and cushion material in the same armrest. (A) is an AA arrow sectional view of FIG. 1, (B) is a BB arrow sectional view of FIG. 1, (C) is a CC arrow sectional view of FIG.

  Hereinafter, a vehicle armrest according to an embodiment of the present invention will be described with reference to the drawings. 1, 2 and 3 (A) and 3 (B) show the longitudinal direction of the vehicle, and in FIGS. 2 and 3 (C), the vehicle compartment side in the vehicle width direction, the car Indicates the outdoor side.

  The armrest 1 is attached to a door trim (not shown), and as shown in FIG. 2, an elongated armrest core 10 extending in the longitudinal direction of the vehicle, a cushion 20 accommodated in the armrest core 10, and FIG. And a skin 30 attached to the armrest core 10 so as to cover the cushion 20 as shown in FIG.

The armrest core 10 has a rear wide portion 10a and a front narrow portion 10b. A pull handle member 2 (shown only in FIG. 3) is fixed to the narrow portion 10b.
As shown in FIGS. 2 and 3, the wide portion 10 a is inclined from the bottom wall 11, the outer wall 12 standing substantially vertically from the outer edge of the bottom wall 11 and the front edge of the bottom wall 11. Front wall 13 extending upward and connected to the outer wall 12, a rear wall 14 extending upward from the rear edge of the bottom wall 11 extending upward and connected to the outer wall 12, and a storage space surrounded by the walls 11 to 14 And 15. The upper side and the compartment side of the accommodation space 15 are open.

  The front wall 13 inclines toward the compartment as it moves forward as shown in FIG. 2, and as it moves forward as shown in FIGS. 3A and 3B, it moves upward. It is inclined to As shown in FIG. 3A, the rear wall 14 inclines upward as it goes rearward.

  As shown in FIG. 2, two rows of brittle fracture lines are set in the armrest core 10. Sites along these brittle fracture lines are more fragile than other sites, and at the time of a vehicle side collision, brittle fractures of sites along these brittle fracture lines are expected to absorb collision energy.

The brittle fracture line on the cabin side is set to cross the approximate center in the width direction of the wide portion 10a, and on this brittle fracture line, a plurality of (six in the present embodiment) lightening holes 16a and 16b are formed. , 16c... Are formed at intervals. A lightening hole 16 a at the front end is formed at the intersection of the bottom wall 11 and the front wall 13. A rear end lightening hole 16 b is formed at the intersection of the bottom wall 11 and the rear wall 14. The lightening holes 16 c are formed in the bottom wall 11.
The brittle fracture line on the outside of the passenger compartment extends along the intersection of the bottom wall 11 and the outer wall 12, and a plurality of lightening holes 17 are also formed in this brittle fracture line.

  As shown in FIG. 2 and FIG. 3, the cushioning material 20 has a shape substantially corresponding to the accommodation space 15 of the armrest core 10 and has a substantially horizontal lower surface 21 in contact with the bottom wall 11 and an outer wall A generally vertical outer surface 22 tangent to 12, an inclined front surface 23 tangent to the front wall 13 and an inclined rear surface 24 tangent to the rear wall 14.

  The cushioning material 20 does not correspond to the shape of the housing space 15 at the following two points. The first point is that the recess 25 is formed on the lower surface 21 of the cushion member 20 over a wide area excluding the peripheral portion. The second point is that a plurality of (three in the present embodiment) fitting projections 26, 27, 28 are formed on the cushion member 20 so as to protrude downward.

  As shown in FIG. 3 (B), the fitting convex portion 26 of the cushion material 20 is fitted into a lightening hole 16a (fitting hole) on the front end on the brittle fracture line on the vehicle compartment side. As shown in A), the fitting projection 27 is inserted into the lightening hole 16b (fitting hole) at the rear end on the brittle fracture line on the vehicle compartment side, and the fitting projection 28 is brittle fracture on the outside of the vehicle compartment. It is inserted into a lightening hole 17 (fitting hole) located approximately at the center of the line. Thus, since the cushioning material 20 can be set without using an adhesive, the workability is good.

  The cushioning material 20 is formed of a material having a relatively high elastic repulsive force. Since the cushion material 20 bears a load in the area excluding the recess 25 until the depression 25 of the cushion material 20 is crushed when the occupant places the elbow, the elastic repulsive force is weak. Therefore, good tactile sense can be secured. When a large load is applied and the sinking exceeds a predetermined amount, the recess 25 is crushed and the cushion material 20 bears the load over the entire area, so that the elastic repulsive force becomes strong. As a result, sinking can be suppressed.

  The present invention is not limited to the above embodiment, and various aspects can be adopted.

  The present invention can be applied to a vehicle armrest attached to a door trim or the like.
