Electro-pneumatically controllable removable automobile seat cover

Abstract

The present innovation relates to the field of automotive seat covers, and more specifically to a seat cover which is equipped with an electro-pneumatic control system comprising multiple pneumatic bags and can preferably be used in trucks. The cover functions as an ergonomic mechanism incorporating an integrated electrical system, including a power shut-off button for disconnecting the power supply when necessary. The system also distributes controlled amounts of air, supplying air to the pneumatic bags of the ergonomic cover. Accordingly, the air is selectively directed to the desired bags, allowing each bag to operate independently.

[0001] DESCRIPTIVE REPORT

[0002] Removable car seat cover with electro-pneumatic control.

[0003] Field of invention

[0004] [1] The present innovation falls within the field of automotive seat covers, more specifically in a cover equipped with electropneumatic control composed of multiple pneumatic bags that can preferably be used in trucks. This cover acts as an ergonomic mechanism that uses an integrated electrical system, including a button for power interruption when necessary. This system also distributes doses of air in a controlled manner, providing air to the pneumatic bags of the ergonomic cover. With this, the air is selectively directed to the desired bags, allowing each one to operate independently.

[0005] Fundamentals of innovation

[0006] [2] A seat cover, as the name suggests, is an accessory designed to cover and protect the seat, serving the function of preserving it against wear, dirt and damage caused by daily use. In addition, its application aims to offer greater comfort to the user. In contemporary society, the automobile has become an indispensable means of transport, keeping pace with the fast-paced lifestyle and the need for practical mobility. The growth of the automotive trade has driven a significant increase in car ownership among residents, making comfort inside vehicles an increasing priority.

[0007] [3] During driving, especially on long journeys, the driver remains seated in the vehicle seat for extended periods, which can cause discomfort, mainly due to the characteristic rigidity of conventional automotive seats. Although seats are designed to offer

[0008] Petition 870250008429, dated 01 / 31 / 2025, page 6 / 18 support, they do not always fully meet the ergonomic and comfort needs of all users. It is in this scenario that the chair cover stands out, offering a practical and efficient solution.

[0009] [4] Using a seat cover provides a more comfortable and adaptable surface to the user's needs, helping to reduce discomfort while driving. In addition, the cover acts as an additional protective element, preserving the integrity of the original seat and extending its lifespan. Thus, the seat cover not only improves the driver's experience while driving, but also adds value to the vehicle by keeping the interior in good condition.

An air pump is integrated into the side wall of the backrest cover, allowing the airbags to operate. During use, the air pump is activated by a control switch, inflating the three airbags independently.

[0012] [7] WO2016029834 is a cover that includes one to eight additional fixed or removable pockets, designed to accommodate adjustable-size and shape cushions made of elastic or inelastic material. The cushions may contain manually inflated air bags for added comfort.

The seat cover includes a main body, with the airbag cushion positioned in the backrest or on the rear surface thereof. The airbag is filled with a controlled amount of gas, which adjusts dynamically when the user leans against the backrest. The movement of the gas inside the airbag allows for automatic and comfortable adjustment, providing ideal support to the lumbar region.

[0010] KR101770306 refers to a vehicle seat cover, with a main body consisting of an upper and lower cover, integrating seat and back panels. A spacer creates a pocket for a wind blower that provides ventilation. The upper cover, composed of fabric bonded to a cushion, has ventilation holes with eyelets that connect the ventilation system to the interior space. The design offers comfort, stability for the driver, and efficient ventilation.

[0016]

[0011] Unlike previous inventions, the present innovation is a removable car seat cover with preferably electro-pneumatic or pneumatic control, composed of three main parts - seat, backrest and headrest - interconnected by fastening straps. Internally, it has strategic cavities for pneumatic bags connected by hoses and valves to a central control. The headrest has three pneumatic bags, is height-adjustable and fixed by adjusting straps. The backrest has three bags in the cervical region and two lateral ones, while the

[0018]

[0012] The present innovation has the advantage of being widely versatile, being usable in various vehicles and also in office chairs, due to its portability. Furthermore, it eliminates the need for compressed air from trucks, as it is compatible with mini compressors, allowing its adaptation to different usage contexts.

[0027]

[0020] The present innovation relates to a cover (1) for automobile seats, specially designed with a fabric suitable for its purpose. This cover (1) is preferably intended for large vehicles, such as trucks, and was developed to be applied over the seat (A) in a practical and functional way, providing greater comfort to the user.

[0028]

[0021] Figure 1 shows an exploded view of an example of use. In this configuration, a seat (A) is illustrated, preferably from vehicles that have compressed air systems, such as those common in trucks. The same figure details the cover (1) in exploded and cutaway views, highlighting its structure divided into three main parts: the seat (10), the backrest (11) and the headrest (7). These parts are interconnected by fastening straps (9) with Velcro, which ensure their secure and stable attachment to the vehicle seat.

[0029]

[0022] Inside the cover (1), there are strategically designed cavities to house air bags (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h). These bags are connected by a system of hoses (3) and valves, which perform the function of controlling the airflow. The air is supplied by a main hose (6), which connects to the vehicle's compressor (12). The control (5), manually operated by the user, regulates the operation of the valves, allowing individual adjustment of the air bags according to the user's needs.

[0030]

[0023] The headrest (7), also illustrated in Figure 1, is designed to be movable and contains cavities to house three pneumatic bags, two lateral (2a) and one central (2b). This headrest is designed to be height adjustable using adjusting straps (8) that allow vertical movement. After adjustment, the headrest is fixed in the desired position by means

[0031] Petition 870250008429, dated 01 / 31 / 2025, page 10 / 18 of a fastening system (4), which preferably uses velcro for greater practicality.

[0032]

[0024] In the backrest section (11), the air bags are arranged within strategically located cavities. In the central region, intended for cervical support, three bags (2c, 2d and 2e) are positioned vertically and separated to provide uniform support. On the sides of the seat, two bags (2f) are located, one on each side, which contribute to the lateral support of the user's body. The seat (10) has three cavities for bag placement, being the central bag (2g) and two lateral ones (2h).

[0033]

[0025] The system operation is detailed in Figure 6. The vehicle's compressor directs air through the main hose (6), which connects to the control inlet (5). This control has independent buttons (12), designed to control each air bag individually, allowing customized adjustments for the bags (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h). From the control outlet (5), the hoses (3) carry air to the valves, which regulate the amount of air directed to each air bag.

The invention should be understood in its broad scope, and it is possible that many modifications and different representations may be developed from the descriptions and drawings presented. The innovation is not restricted to the specific form disclosed and should be interpreted as encompassing any alterations or variations that are within the scope of the appended claims. Although specific terms are used, they are merely descriptive and are not intended to limit the innovation in any way.
