  Instead of laying the floor mat after attaching the lower-limb protection shock absorbing member to the floor panel first, in order to simplify the process and man-hour to attach the lower-limb protection shock absorbing member and floor mat to the floor panel It is desirable to attach a shock absorbing member for protecting the lower limbs in advance to the back surface of the floor mat and attach it to the floor panel together with the floor mat.

However, on the front seat side of the car, there is a tire space at the end, a body at the side, a dashboard on the upper side, and a brake, accelerator, etc. on the floor panel side. Is narrow.
For this reason, it is necessary to carry in the floor mat in a state where it is folded from the door side. However, since the impact absorbing member for protecting the lower limbs cannot be folded, there is a problem that the carrying-in work is troublesome.
In addition, there is a problem that it takes time to accurately lay the floor mat on which the shock absorbing member for protecting the lower limbs is attached to the floor panel in a narrow work space.

  Furthermore, when it becomes necessary to make fine adjustments after attaching the floor mat, it may be necessary to lift the floor mat. In this case, the shock absorbing member for protecting the lower limbs is composed of one part. If this is the case, the floor mat could not be lifted up well, and workability could be reduced.

  Therefore, it is conceivable to divide and configure the impact absorbing member for protecting the lower limbs into two parts, but it takes time and effort to stick the impact absorbing member for protecting the lower limbs composed of two parts to the floor mat, After the floor panel is carried into the vehicle, the relative position of the two parts is displaced due to the loosening of the floor mat, etc., and it may take time for installation and adjustment after installation.

  An object of the present invention is to provide a shock absorbing member for protecting a lower limb that can be easily attached to an automobile and adjusted after the attachment.

In order to solve the above problems, the shock absorbing member for protecting the lower limbs of the present invention,

The lower limb protection impact member is constituted by connecting a first member closer to the center in the width direction of the vehicle body and a second member arranged outside the first member by a flexible connecting portion. .

  According to the present invention, the shock absorbing member for protecting the lower limb part is composed of the first member and the second member, and the first member and the second member are connected by the connecting portion. At the time of sticking, it can be handled as one component, and the first member and the second member are not displaced relative to each other, and workability is good.

  Further, since the connecting portion can be bent, the first member and the second member can be bent together like a hinge. Accordingly, the floor mat can be folded in a state where the lower limb protection impact absorbing member of the present invention is adhered to the floor mat, and the efficiency of the work for carrying into the vehicle can be increased as much as possible. The time required for laying can be shortened.

  Further, after laying the floor mat with the shock absorbing member for protecting the lower limbs of the present invention, the first member and the second member are connected even when the mounting position of the shock absorbing member for protecting the lower limbs is necessary. Since it bends at the part, it is easy to lift the floor mat from the end. In addition, the floor mat can be greatly lifted by bending at the connecting portion as compared with the case where the impact absorbing member for protecting the lower limbs is made of one component.
