Description

Technical Field

[0001] The invention belongs to the technical field of automobile seats, and in particular relates to an automobile rear seat which can be unfolded and adjusted, folded and stored. Background Art

[0002] The aforementioned deployable adjustability means that the rear seats of the car can be adjusted forward and backward through sliding rails in the unfolded state. The advantages are: improving riding comfort, passengers can adjust the seat position as needed to obtain a more comfortable leg position, which is especially important for long-distance rides; flexibly allocating space, the front and rear adjustment function can flexibly allocate the space in the car according to the luggage needs of the passengers, thereby enhancing practicality; facilitating entry and exit, adjusting the position of the rear seats can provide convenience for passengers to enter and exit the vehicle, especially for children or people with limited mobility; adapting to different body shapes, the front and rear adjustment can adapt to the needs of passengers of different heights and / or body shapes, ensuring a suitable sitting posture; enhancing carrying capacity, by adjusting the rear seats, the trunk space can be expanded to place large items; improving safety, the appropriate seat position helps passengers use seat belts, thereby improving safety; improving riding experience, passengers can adjust the seat position according to their preferences, thereby improving the overall riding experience; adapting to multiple uses, the front and rear adjustment can adapt the vehicle to different scenarios, such as family travel, business reception or cargo needs, etc.

[0003] The aforementioned foldable and storable means that the rear seats of the car can be stored in the trunk of the car in a folded state. The advantages are: maximizing the cargo space, folding and storing in the trunk, making it convenient to place large items; flexible space utilization, flexible adjustment of the interior space layout according to the needs of carrying people or goods; easy cleaning; improved practicality, when the rear seats are not needed, more space can be freed up for the trunk; improved loading convenience, after the seats are stored, the trunk opening is larger, which is convenient for the placement of large items, etc.

[0004] In the public Chinese patent documents, there is technical information about folding the rear seats of a car and storing them in the trunk. A typical example is CN222473978U which recommends "a car seat that is convenient to fold and store". By reading the patent specification, especially paragraphs 0038 to 0039 of the specification, it can be seen that: during normal use, that is, when unfolded, the angle between the seat back and the seat is adjusted to a degree suitable for sitting by the recliner; when folding, the soft cable drive member is manually pulled to unlock the ground lock and the recliner on the floor of the trunk, so that the seat back is folded towards the seat and then flipped into the storage slot of the trunk.

[0005] The above CN222473978U can achieve the technical effects recorded in paragraphs 0014 to 0016 of its specification, but there is still a shortcoming of losing one thing for another: like the vehicles such as hatchbacks, MPVs, SUVs, etc. seen in the market so far, the rear seats can be folded and stored in the trunk after being turned over, but in the unfolded state, the lack of adjustment function cannot reflect the many advantages of the applicant mentioned above that the front and rear adjustment is achieved through the slide rail. The reason why there is a situation where the "bear paw" and "shark fin" cannot be achieved at the same time, that is, the reason why there is a situation where the seat cannot be adjusted front and rear in the unfolded state and stored in the trunk in the folded state, the applicant believes that in addition to the main bias in technical design, it is also affected by many superficial phenomena. In terms of technical design bias, the industry generally believes that the forward and backward sliding adjustment function of the car seat in use is guaranteed by a pair of slide rails arranged parallel to each other, and the slide rails include a static slide rail and a movable slide rail that forms a sliding pair with the static slide rail, and the static slide rail is immovably fixed to the floor of the car compartment, so the car seat that needs to be folded and flipped into the trunk cannot meet the forward and backward position adjustment requirements in the unfolded state when the passengers are sitting; the rear seats seem to focus more on comfort and space utilization rather than flexibility, and the slide rail function does not conform to this kind of design concept. So it is believed that only one of the two can be chosen. In terms of the influence of many surface phenomena, one is that it is limited by space, because the design of the storage cavity is to maximize the trunk space, and adding slide rails will take up more space; the second is that the slide rail will increase the complexity of the seat structure; the third is that the occupancy rate of the rear seats is relatively low.

[0006] The applicant believes that the loss of the function of adjusting the rear seats forward and backward in exchange for the expansion of the loading space by folding and storing is a violation of the humanistic concept of people-oriented. In addition, since the above CN222473978U is manually operated during the process of folding and storing in the storage slot of the trunk, it is relatively laborious to operate on the one hand, and there is a risk of collision on the other hand, because impact and collision are inevitable during the process of introducing the seat into the storage slot, and there is a risk of safety, because once the seat is accidentally dropped during the flipping process, the destructive damage to the seat is self-evident. Summary of the invention
