Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automobile seat structure equipped with a folding mechanism.

[Prior Art] Automobile seat structures that are equipped with a folding mechanism that can be folded and stored as needed from a normal upright position are generally well known. For example, in Japanese Utility Model Application Publication No. 1-120430, for a rear seat side seat, after a seat pack is stacked on a seat cushion and folded, the seat cushion is rotated forward using its front mounting portion as a fulcrum. discloses a seat that can be folded and stored toward the front of the vehicle body.

By folding the rear seat and storing it closer to the front of the vehicle body than the normal upright position, the luggage storage space provided behind the rear seat can be expanded.

In addition, when this space is expanded to store relatively large items, even when forward inertia is applied to the items, such as during sudden braking, the seat stored in a predetermined position will move the items forward. Movement can be prevented.

[Problems to be Solved by the Invention] However, in the conventional sorting structure described above, it is true that for relatively large items, the storage space can be expanded by folding the seat, and the storage space can be expanded by folding the sheet, and the storage space can be prevented from moving forward. However, since it can only be folded toward the front of the vehicle, even if the cargo to be loaded is much smaller than the storage space in the normal seat upright position, the storage space behind the seat will be adjusted accordingly. Therefore, it is difficult to effectively prevent back and forth movement of luggage, and it is also inconvenient to load and unload luggage.

Furthermore, in the past, even if there was no luggage to be loaded or the luggage was small as mentioned above, at least the above-mentioned normal storage space or the rear of the seat was provided, which ensured more living space inside the vehicle. It was a disadvantage at the top.

This idea was made in view of the above problems, and the rear space of the sorter can be expanded or reduced depending on the size of the cargo to be loaded or the request for expansion of the living space inside the vehicle. The purpose of this invention is to provide a seat structure for automobiles that can be used in various ways.

3 Means for Solving the Problems] Therefore, the first invention of the present application provides a sorting structure for an automobile equipped with a folding mechanism, in which the sorting is carried out at a position that is higher than the seat position in the normal upright state of the vehicle body. It is provided with a folding mechanism that can be selectively folded and stored toward the front side or the rear side of the vehicle body.

Further, the second invention of the present application is the first invention,
The front and rear legs of the seat are provided with locking means for locking each leg to the vehicle body, and when one of these locking means is unlocked, the other locking means is held in a locked state. A holding means is provided to hold the object.

``Effects of the Invention According to the first invention of the present application, there is provided a folding mechanism that can selectively fold and store the sort toward the front side of the vehicle body or the rear side of the vehicle body from the seat position in the normal upright state. When the cargo to be loaded is large, the seat can be folded and stored closer to the front of the vehicle than its normal seat position in the upright position, expanding the space behind the seat and securing storage space for the cargo. On the other hand, if the cargo to be loaded is small,
By folding and storing the seat to the rear of the vehicle body compared to the seat position in its normal upright position, the space behind the seat can be reduced and luggage can be effectively prevented from moving forward when braking suddenly. Furthermore, when there is no cargo to be loaded or the cargo is small, and you want to make more space inside the vehicle, the space behind the seat can be reduced by folding the seat from its normal upright position to the rear of the vehicle. This allows you to expand your living space accordingly. In other words, the space behind the seat can be expanded or contracted depending on the size of the luggage to be loaded, or in response to requests for expansion of the living space inside the vehicle.As a result, storage space can be secured according to the size of the luggage. By doing so, it is possible to improve cargo handling efficiency and to effectively prevent cargo from moving forward during sudden braking. Furthermore, the interior space of the vehicle can be used more effectively depending on the presence or absence and size of cargo to be loaded.

Further, according to the second invention of the present application, in the first invention, when either one of the locking means provided on the front leg and the rear leg of the seat is unlocked,
Since the holding means for holding the other locking means in the locked state is provided, either the locking means for the rear legs or the front legs can be unlocked to move the seat forward or backward from the seat position in the upright state. Even when the device is selectively folded and stored, either one of the other locking means can be maintained in a locked state. In other words, even if the seat can be selectively folded toward the front or rear of the vehicle, the front and rear legs will not be unlocked at the same time when the seat is folded; The seat can be securely locked against the vehicle body.

That is, while maintaining the same effect as the first invention, safety can be ensured by reliably preventing forward movement of the cargo during sudden braking or the like.
