Description

TECHNICAL FIELD The present invention relates to a spare tire mounting method for mounting a spare tire in the luggage compartment of a vehicle.

2. Description of the Related Art Conventionally, there has been known a vehicle in which a spare tire, which is used when an attached tire is damaged, is stored in a luggage compartment (trunk room) provided at the rear part of the vehicle body.

For example, Patent Document 1 discloses a closed cross-sectional shape portion formed by a partition panel and a reinforcement member by attaching a reinforcement member to a location facing a spare tire in a partition panel separating a trunk room and a cabin. is disposed in the vicinity of the front side of the spare tire.

JP-A-09-052582

According to the above Patent Document 1, even if the spare tire unexpectedly moves forward (toward the seated occupant), it is received by the high-strength closed cross-sectional shape portion of the partition panel, and the closed cross-sectional shape portion is provided with the spare tire. By accommodating a part of the spare tire in the recess, it is said that a sufficient storage space for the spare tire is ensured in the trunk room.

However, although the technique disclosed in Patent Document 1 can be applied to sedan-type vehicles with partitions, it is difficult to apply it to vehicles without partitions, such as hatchbacks and single-box vehicles. Further, in Patent Document 1, only a part of the spare tire is accommodated in the concave portion, and there is room for improvement in terms of ensuring storage space for luggage other than the spare tire.

Here, in order to make effective use of the space in the trunk room (to ensure luggage room capacity), it is conceivable to arrange a spare tire under the deck board. However, in electric vehicles and fuel cell vehicles, for example, since structures such as batteries and fuel tanks are mounted under the deck board, there is often no space under the deck board for accommodating a spare tire. . For this reason, in order to secure luggage room capacity, these vehicles generally carry a puncture repair kit instead of a spare tire, which takes up less space than the spare tire.

However, in rough road areas where road maintenance is not advanced, it is not uncommon for the installed tire to be damaged while driving, so there is a strong demand for a spare tire instead of a puncture repair kit. There is no choice but to mount the tires on the deck (inside the trunk room), often sacrificing luggage space.

The present invention has been made in view of this point, and its object is to provide a spare tire mounting method capable of minimizing the reduction in cargo room capacity when a spare tire is mounted, regardless of the type of vehicle. to provide.

In order to achieve the above object, in the spare tire mounting method according to the present invention, the recess on the back side of the design surface of the spare tire placed on the floor surface of the luggage compartment is used as a storage space for other luggage. .

Specifically, the present invention is directed to a spare tire mounting method for mounting a spare tire in the luggage compartment of a vehicle.

In this spare tire mounting method, the spare tire is placed on the floor surface of the luggage compartment so that the design surface of the spare tire faces the floor surface of the luggage compartment, and the design surface of the spare tire is placed on the floor surface of the luggage compartment. The spare tire is fixed to the floor surface via a belt looped around the spare tire so that the recess on the back side of the spare tire is opened.

In the present invention, the “design surface” refers to the surface facing outward in the vehicle width direction when the spare tire is mounted, and the “concave portion” is used to accommodate disc brakes, hubs, etc. when the spare tire is mounted. , refers to the depression on the back side of the design surface.

According to this configuration, the spare tire is fixed to the floor surface via the belt that is wrapped around the spare tire placed on the floor surface of the luggage compartment. can be suppressed from moving forward (toward the seated occupant).

Moreover, the spare tire is placed so that its design surface faces the floor surface of the luggage compartment, and the belt is hung so that the recess on the back side of the design surface of the spare tire is opened. The recess can be used as a storage space for luggage, thereby minimizing the reduction in luggage compartment capacity when a spare tire is installed, regardless of the type of vehicle.

In addition, since the concave portion of the spare tire is used as a storage space for luggage, the concave portion (the wall surface of the wheel) prevents the luggage from falling or collapsing, so it is possible to suppress the luggage from being scattered in the luggage compartment.

As described above, according to the method for mounting a spare tire according to the present invention, it is possible to minimize the reduction in luggage compartment capacity when the spare tire is mounted, regardless of the type of vehicle.
