Description

  The present invention relates to a structure for locking a side end portion of a floor carpet covering a vehicle body floor surface to a locking member attached to the vehicle body floor side portion.

  As a structure for locking a side end portion of a floor carpet covering a vehicle body floor surface, for example, Patent Document 1 discloses a structure for locking a retainer fixed to a side end portion of a floor carpet to a locking member on the vehicle body side. Is disclosed. However, this structure requires a large number of retainers for separate parts, and requires a process of fixing each retainer to the end of the floor carpet in advance with a stapler, etc., which increases the number of parts and assembly man-hours. There was a problem.

  On the other hand, in Patent Document 2, a slit is provided directly at the end of the floor carpet, and the slit is covered with an edge of a scuff plate (side sill scuff) in a state of being locked to a locking member attached to the vehicle body side. A structure for holding down is disclosed. However, in this structure, when a tensile stress in the surface direction acts on the end portion of the floor carpet, the slit may be expanded and exposed downward from the edge portion of the scuff plate. There was a problem that the end of the slit was easily damaged due to the stress concentration.

JITTO No. 2576752 JP 2007-99009 A

  The present invention has been made in view of such a situation, and an object of the present invention is to provide a vehicle floor capable of reliably locking a side end with a small number of parts and assembly steps and preventing damage to the side end. It is in providing the side edge part locking structure of a carpet.

  In order to solve the above problems, the present invention provides a structure in which a side end portion of a floor carpet covering a vehicle body floor surface is locked to a locking member attached to the vehicle body floor side portion. A pair of locked holes are formed side by side in the vehicle front-rear direction, and the locking member is provided with a pair of front and rear locking protrusions engageable with the pair of locked holes. A latching portion extending in a direction away from the other latching projection is provided at the upper end of one latching projection.

  In a preferred aspect of the present invention, the pair of locked holes are round holes. Further, the protruding height of the other locking projection is equal to or higher than the height to the lower surface of the hooking portion. Further, the one locking projection is disposed behind the other locking projection in the vehicle front-rear direction, and the latching portion extends rearward in the vehicle front-rear direction from the upper end of the one locking projection. .

  In another preferred aspect of the present invention, the locking member includes an electrical harness holding portion that is routed along the side of the vehicle body floor, and the pair of locking projections are provided on the vehicle with respect to the electrical harness. The floor carpet side end part which is arrange | positioned at the chamber center side and covers the said electrical equipment harness is latched in a bending state.

Since this invention is comprised as mentioned above, it has an effect as described below.
(1) It is only necessary to provide a pair of locked holes at the side end of the floor carpet, and a separate mounting member such as a retainer is not required, so the number of parts and assembly man-hours can be reduced. The tensile stress in the surface direction is dispersed in the two locked holes arranged side by side in the vehicle front-rear direction, and deformation and breakage of the locked hole due to stress concentration can be prevented.
(2) In addition to reducing the tensile stress acting on each locked hole, each locked hole can be made small, so that the amount of expansion of each locked hole during tensile stress is small. Therefore, the locked hole can be reliably prevented from being exposed from the lower end of the side sill scuff, and the overlap of the side sill scuff can be set small.
(3) Since the floating portion of the floor carpet side end is restricted by the latching portion of one latching projection, the other latching projection adjacent to the latching projection can be pulled out without providing the latching portion. It is suppressed and can exert a locking force in the surface direction. Thus, if the locked hole corresponding to one locking projection is hooked and locked first, the locked hole corresponding to the other locking projection is automatically positioned and can be locked immediately. Therefore, assembly work can be performed easily and without difficulty.
(4) Since the engagement between the other locking projection and the locked hole is a simple insertion without a hook, assembly is possible even if the tolerance between the other locking projection and the locked hole is reduced. On the other hand, since one positioning hole is not required to be positioned precisely, it is possible to set a dimensional tolerance giving priority to assembly.

  In the present invention, in the embodiment in which the pair of locked holes are round holes, the stress concentration can be relaxed compared to the conventional slit-shaped locked holes, and deformation and breakage of the locked holes can be more reliably prevented. it can. Moreover, the downward expansion of the locked hole is prevented, and it is not exposed from the lower end of the side sill scuff.

  In the present invention, in the aspect in which the protruding height of the other locking projection is equal to or higher than the height to the lower surface of the latching portion, the upper limit position of the floor carpet is regulated by the lower surface of the latching portion of the one latching projection. By doing so, it is possible to reliably prevent the floor carpet from being pulled out from the other locking projection having no similar latching portion.

  In the present invention, the one locking protrusion is disposed behind the other locking protrusion in the vehicle front-rear direction, and the latching portion extends rearward in the vehicle front-rear direction from the upper end of the one locking protrusion. In this aspect, when a force toward the front of the vehicle is applied to the floor carpet, the locked hole is reliably prevented from being pulled out from the hooking portion.

  In the present invention, the locking member includes an electrical harness holding portion that is routed along the side of the vehicle body floor, and the pair of locking projections are disposed on the vehicle compartment center side with respect to the electrical harness. In the aspect where the floor carpet side end covering the electrical harness is locked in a bent state, the locked hole is locked in the middle upper part of the locking protrusion by the surface rigidity of the floor carpet, There is an allowance for the locked hole of the floor carpet to move downward, which reduces the load on the locked hole and is advantageous in preventing deformation and breakage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In the figure, side sills 3 and 3 are provided along the left and right end portions of the vehicle body floor 1, a center tunnel is formed in the center of the vehicle body floor 1, and the left and right side sills 3 and 3 are connected. A floor cross member is provided. The floor carpet 2 is formed of a molded product corresponding to such a floor shape.

  A plurality of mounting holes 30 are formed on the upper surfaces of the left and right side sills 3 and 3 with appropriate intervals in the vehicle front-rear direction, and a locking member for the side end 23 of the floor carpet 2 is provided in each mounting hole 30. A harness clamp 4 is also attached. As shown in FIGS. 2 and 3, each harness clamp 4 is provided with a holding portion 45 of an electrical harness 5 that is routed along both left and right ends of the vehicle body floor surface 1, and on the side of the floor carpet 2. Locking protrusions 41 and 42 that engage with the locked holes 20 (21 and 22) formed in the end 23 are provided.

  The harness clamp 4 is made of an injection-molded product using a resin material, and includes a board 40 extending in the vehicle front-rear direction, a clip 43 protruding from the bottom of the front end of the board 40, and a bottom of the rear end of the board 40 And a harness holding part 45 provided integrally on the upper part near the front end of the board 40, and a pair of front and rear is provided at the edge of the center side of the passenger compartment near the rear end of the board 40. The locking protrusions 41 and 42 are integrally formed. The holding portion 45 in the illustrated example is formed in a flexible binding band shape, and the electric harness 5 can be bound and held by inserting and locking the band tip portion into a slit that penetrates the substrate 40 laterally. However, the form of the holding portion 45 is not limited to this.

  The locking protrusions 41 and 42 are provided at the edge of the board 40 on the center side of the passenger compartment, and the holding part 45 is provided at the edge of the opposite side. Of the pair of locking projections 41, 42, the upper end of one locking projection 41 disposed rearward in the vehicle front-rear direction extends away from the other locking projection 42, that is, rearward in the vehicle front-rear direction. The extended latching part 41a is integrally formed. On the other hand, the locked hole 20 of the floor carpet 2 includes a pair of front and rear locked holes 21 and 22 that are formed side by side in the vehicle longitudinal direction corresponding to the pair of locking protrusions 41 and 42. Each of the locked holes 21 and 22 is a circular hole having the same shape, and is formed when the floor carpet 2 is formed.

  The harness clamp 4 configured as described above is fixed in a state where the leg portion 44 is in contact with the upper surface of the side sill 3 by fitting the clip 43 into the mounting hole 30. As shown in FIGS. 2 and 3, the electrical harness 5 held by the holding portion 45 of the harness clamp 4 is routed closer to the vehicle side with respect to the locking protrusions 41 and 42.

  When the side end 23 of the floor carpet 2 is locked to the harness clamp 4 that holds the electrical harness 5, first, the locked hole 21 on the vehicle rear side is set to the latching portion 41 a of the corresponding locking protrusion 41. Is engaged with the base 41b of the locking projection 41. Then, the locked hole 22 on the front side of the vehicle is automatically guided to the other locking projection 42, and the locked hole 22 becomes the locking projection 42 only by pushing down the side end 23 of the floor carpet 2. Can be engaged.

  Thereafter, as shown in FIGS. 4 and 5, the side sill scuff is placed on the upper side of the side end portion 23 of the floor carpet 2 that covers the electrical harness 5 (holding portion 45) and is locked in a bent state by the locking protrusions 41 and 42. 6 and the side sill scuff 6 covers the side end 23 of the floor carpet 2 together with the electrical harness 5 and the harness clamp 4.

  In the locking structure of the floor carpet side end 23 as described above, when a force that pulls down the floor carpet 2 is applied, the tensile force is distributed to the two locking protrusions 41 and 42, thereby In addition to reducing the load on the locked holes 21 and 22, each locked hole 21 and 22 has a small round hole shape, so that the edges of the locked holes 21 and 22 are pulled. The stress is dispersed and deformation and breakage of the locked holes 21 and 22 are prevented. Moreover, the deformation | transformation of each to-be-latched hole 21 and 22 can be set short, the edge part of the side sill scuff 6 can be set short, and the part | minute weight can be reduced.

  Furthermore, as shown in FIG. 5, the upper end of the other locking projection 42 is set higher than the lower surface of the latching portion 41a of the one locking projection 41, so that the upper direction of the floor carpet side end portion 23 is increased. The movement is restricted by the lower surface of the latching portion 41a, and the latched hole 22 of the floor carpet side end portion 23 is prevented from being pulled out from the latching protrusion 42 without the latching portion.

  Further, due to the surface rigidity of the floor carpet 2, the locked holes 21, 22 are locked at the middle upper part of the locking protrusions 41, 42, and the locked holes 21, 22 of the floor carpet 2 are accordingly lowered. This is advantageous in that there is a margin of movement in the direction, the load on the locked holes 21 and 22 is reduced, and deformation and breakage are prevented.

  In addition, the floor carpet 2 that will be stepped on by the occupant's feet seated in each seat in the state where the seat is installed in the vehicle compartment, as seen from the fact that the floor mat is easily displaced forward, There is a tendency for force to act. In addition, on the driver's seat side, a force in the forward direction of the vehicle acts on the floor carpet 2 also by a pedal operation. The configuration in which the latching portion 41a of the one latching protrusion 41 extends toward the rear of the vehicle prevents the latched holes 41 and 42 from being pulled out against such a tensile force in the vehicle front direction. This is advantageous.
