Description

  The present invention relates to a vehicle heater duct that supplies hot air from a vehicle heating device to a rear seat of the vehicle.

  FIG. 3 is a schematic diagram of the automobile 10 in which the vehicle heater duct is incorporated. As illustrated, the automobile 10 includes a three-row seat including a front row seat 11, a middle row seat 12 and a rear row seat 13. The front unit 14 is installed at the front of the automobile 10, and the rear heater unit 15 is installed on the floor near the front row seat 11. A vehicle heater duct 16 is connected to the rear heater unit 15, is disposed to the vicinity of the rear row seat 13 through a passage between the middle row seats 12, 12, and is arranged from the opening 16 a at the end of the vehicle heater duct 16 to the rear row. It is configured so that warm air is blown out to the feet of the passengers in the seat.

  As shown in FIG. 4, the vehicle heater duct 16 is disposed on the upper surface of the floor panel 17 so as to be embedded in the felt 18, and a floor carpet 19 is laid on the felt 18.

  However, since the heater duct 16 is disposed on the passage through which the occupant passes, it is often stepped on by the occupant. If the heater duct 16 is stepped on, the shape of the heater duct 16 may be deformed or damaged.

  A vehicle heater duct according to claim 1 is a vehicle heater duct that supplies warm air from a heating device of a vehicle to a rear seat of the vehicle, a duct body that guides the warm air from the heating device, and a longitudinal direction of the duct body. A protective cover that projects from the upper end of the side surface and covers both side surfaces, and a reinforcement that is foldably connected so as to overlap the inner side surface of the protective cover and the back surface of the duct body via a hinge that is a crease at the end of the protective cover And a cover.

  According to the vehicle heater duct of the first aspect, by covering the both sides of the duct main body with the protective cover and further connecting the reinforcing cover, it is possible to prevent deformation or breakage of the shape even if the passenger is stepped on. it can. Here, since the reinforcing cover is connected to the protective cover via a hinge formed of a crease, both covers can be integrally formed by resin molding.

  Moreover, like the heater duct for vehicles which concerns on Claim 2, it has a trough part formed by the inner surface of a protective cover, and the side surface of a duct main body, and a reinforcement cover has a peak part fitted to a trough part via a hinge. If comprised so that it may have, both covers can be closely_contact | adhered and rigidity can be improved as a whole.

  Further, as in the vehicle heater duct according to the third aspect, the first hole portion for driving the locking tool is formed in the overlapping portion of the protective cover and the reinforcing cover, and the protective cover and the back surface of the duct body are overlapped. If the second hole portion for driving the locking tool is formed in the mating portion, the two covers are attached to the duct main body by driving a locking tool such as a rivet or a staple into the first and second hole portions. Can be firmly fixed.

  According to the vehicle heater duct of the present invention, it is possible to prevent the heater duct body from being deformed or damaged.

It is a figure which shows the heater duct for vehicles by embodiment of this invention, Fig.1 (a) is a top view, FIG.1 (b) is a back view, FIG.1 (c) is a side view, FIG.1 (d) is a front view. It is. It is an expanded sectional view in the AA line of Fig.1 (a). It is a schematic diagram of the motor vehicle in which the heater duct for vehicles of the prior art example was incorporated. It is an expanded sectional view in the BB line of FIG.

  Next, the heater duct 20 for vehicles by embodiment of this invention is demonstrated based on FIG.1 and FIG.2. The vehicle heater duct 20 is installed at the same position as the conventional vehicle heater duct 16 shown in FIG.

  As shown in FIG. 1, the vehicle heater duct 20 includes a cylindrical duct body 21 that guides warm air from a heating device such as a rear heater unit, and the both sides of the duct body 21 project from the upper end of the side surface along the longitudinal direction of the duct body 21. A protective cover 22 and a reinforcing cover 23 are provided. The reinforcing cover 23 is connected to the end portion of the protective cover 22 via a hinge 24 made of a fold so that the reinforcing cover 23 can be folded over the inner side surface of the protective cover 22 and the rear surface of the duct body 21. The protective cover 22 and the reinforcing cover 23 are provided on both side surfaces of the duct body 21, respectively.

  The vehicle heater duct 20 is disposed such that the back surface of the duct body 1 is in contact with the upper surface of the vehicle floor panel. Moreover, the opening 21a at one end of the duct body 21 is connected to the heating device, and is configured such that warm air is blown out from the opening 21b at the other end to the feet of the passengers in the rear row seat.

  The duct body 21, the protective cover 22, and the reinforcing cover 23 are integrally formed by resin molding, and the hinge 24 is formed by a hinge line formed by partially thinning the thickness of the resin and making a crease. Thereby, cost reduction and weight reduction can be achieved without using a special hinge metal fitting.

  The reinforcing cover 23 is overlapped with the back surface of the duct main body 21, but the overlapping portion of the duct main body 21 is made lower than the central non-overlapping portion by the thickness of the reinforcing cover 23, thereby The back surface can be flat.

  Further, the protective cover 22 covers the entire side surfaces along the longitudinal direction of the duct body 20, but the reinforcing cover 23 can be easily folded by connecting it to several partial covers. be able to. In this example, it is divided into three partial covers along the side surface.

  FIG. 2A shows a state where the reinforcing cover 23 is opened on both sides of the side surface of the duct body 21 before the reinforcement cover 23 is bent. In the drawing, the bending direction of the reinforcing cover 23 is indicated by an arrow. FIG. 2B shows a state after the reinforcing cover 23 is bent.

  The vehicle heater duct 20 has a trough portion 25 formed by the inner side surface of the protective cover 22 and the side surface of the duct body 21, and the reinforcing cover 23 is a crest portion 26 that fits into the trough portion 25 when bent through a hinge 24. have. If comprised in this way, both the covers 22 and 23 can be stuck | contacted and rigidity can be improved as a whole.

  Further, as shown in FIG. 2C, a first hole portion 27 for driving the locking tool is formed in the overlapping portion of the protective cover 22 and the reinforcing cover 23, and the back surface of the protective cover 22 and the duct main body 21. When the second hole 28 for driving the locking tool is formed in the overlapping portion with the first and second holes 27 and 28, the first and second rivets and staples are respectively formed in the first and second holes 27 and 28. The two covers 22 and 23 can be firmly fixed to the duct body 1 by driving the two locking tools 29 and 30.

  The vehicle heater duct 20 is disposed on the upper surface of a vehicle floor panel so as to be embedded in the felt, and a floor carpet is laid on the felt.

  In FIG. 2, the hinge 24 that is the fold between the protective cover 22 and the reinforcing cover 23 is located higher than the back surface of the duct body 21, but the hinge 24 is positioned on the same plane as the back surface of the duct body 21. The protective cover 22 and the reinforcing cover 23 may be extended. Thereby, the heater duct 20 for vehicles can be stably installed in the upper surface of the floor panel of a vehicle.
