Description

The present invention protrudes into the vehicle interior side from the cabin side walls of the vehicle, is arranged to extend in the vicinity of the passenger, it relates to an armrest structure for a vehicle occupant example Bei armrest as used as an armrest.

  Generally, an armrest of a vehicle protrudes from the side wall of the vehicle interior toward the interior of the vehicle interior, and a load is applied in the vertical direction because the occupant places an elbow on the armrest, and the armrest has rigidity to withstand the load in the vertical direction.

The armrest having such a configuration is desired to have a structure that does not give an impact to the occupant during a side collision of the vehicle.
Therefore, conventionally, an armrest shock absorbing structure has already been invented.

  In the conventional armrest structure of the vehicle shown in FIG. 12, a boss 104 for mounting an armrest lower 103 is attached to a door trim 101 using screws 102, an arm restorer 105 is provided above the armrest lower 103, and an upper portion of the armrest lower 103 is provided. Ribs 107 and 108 are provided on the upper surface of the horizontal piece 106 and the lower surface of the arm rest portion 105 of the arm restorer 105, and the inclined surfaces 107a and 108a formed on the opposing portions of the ribs 107 and 108 are in contact with each other. (For example, see Patent Document 1).

  In the normal state armrest shown in FIG. 12, when a side impact load is applied to the vehicle, the inclined surface 108 a of the rib 108 of the arm restorer 105 slides along the inclined surface 107 a of the rib 107 of the armrest lower 103. As shown in FIG. 12, the arm restorer 105 jumps upward and deforms to absorb the impact load.

  However, in this conventional structure, as shown in FIG. 12, the lower end of the armrest lower 105 is covered with the upper end of the armrest lower 103 so that the lower end of the armrest 105 is covered with a step (see arrow α). Above, there was a problem that the appearance from the passenger compartment was bad.

Further , as shown in FIG. 13, there is a problem that a sufficient load cannot be absorbed because at least the horizontal piece 106 remains in the same shape as in the normal state even when absorbing the impact load at the time of a side collision.

  In addition, in the normal state, as shown in FIG. 12, since the upper and lower armrests are divided by the inclined surfaces 108a and 107a, there is a problem that the rigidity against the load in the vertical direction is low.

  On the other hand, in the conventional armrest structure of the vehicle shown in FIG. 14, a boss 205 for mounting the armrest lower 204 is attached to the mounting hole 202 of the door trim 201 using a screw 203, and a clip is attached to a horizontal piece 206 above the armrest lower 204. A boss 210 for attaching the arm restorer 209 is attached using 207 and a screw 208 (see, for example, Patent Document 2).

  In the conventional armrest structure of the vehicle shown in FIG. 14, when a side impact load is applied to the vehicle, the occupant and the armrest lower 204 abut against each other. At this time, the boss 205 has an unusually shaped mounting hole 202. The boss 205 itself is displaced in a slanted manner so that the base (vehicle compartment side) of the boss 205 is displaced forward and the head of the screw 203 (vehicle exterior) is displaced rearward. Thus, the arm rest lower 204 is allowed to bend or deform and absorb the impact load.

  However, also in this conventional structure, as shown in FIG. 14, the upper end of the armrest lower 204 is covered with the lower end of the vehicle interior side of the arm restorer 209 to form a step shape (see the arrow β section). In addition, there was a problem that the appearance from the passenger compartment deteriorated.

  In addition, as shown in the figure, there is a problem that sufficient load absorption cannot be achieved because at least the horizontal piece 206 remains in the same shape as in the normal state even when absorbing the impact load at the time of a side collision. 12 to 14, the arrow IN indicates the inside of the vehicle, and the arrow OUT indicates the outside of the vehicle.
