Description

Field of Invention [0001] The present invention is in the field of vehicle body parts. More specifically, the present invention is situated in the context of parts and components for lining the trunk floor of vehicles. Background of the Invention [0002] In a vehicle, the trunk refers to a storage compartment designed for transporting luggage and/or equipment. The trunk is usually located at the rear of the vehicle in an area separate from the passenger compartment, but in some models it can also be found at the front. The main function of the trunk is to provide a safe and convenient space for transporting objects. [0003] To ensure safety and comfort during transport, the trunk floor of a vehicle is lined with a non-slip material. The design and configuration of the trunk may vary depending on the type of vehicle, directly influencing the type of lining required. [0004] This lining is usually a carpet made of materials such as nylon or polyester, which offer wear resistance and ease of maintenance. The lining helps keep luggage and equipment stable while the vehicle is in motion, minimizing the risk of displacement and damage. In addition, its use offers effective sound insulation, reducing noise caused by the movement of items in the compartment. It also facilitates cleaning the trunk and provides an aesthetically pleasing finish to the vehicle, improving the overall perception of quality and comfort of the car's interior. [0005] The trunk lining is designed to conform to the internal shape of the cargo compartment. Its coverage extends to the floor, sides, and, in some cases, the backrest of the rear seats. The lining design is specific to each vehicle model, taking into account variations in size and shape. This adaptation ensures that all areas, including corners and curves, are adequately covered, avoiding unprotected sections. [0006] In some cases, the trunk lining is also designed to include foldable or removable sections that allow access to hidden compartments in the vehicle, such as the specific spaces for the spare tire and the warning triangle, which are usually found inside the trunk and below the lining. [0007] The lining surface can be smooth or textured, depending on the specific needs of the vehicle. The texture, when present, is chosen to improve the grip of stored items, preventing displacement during transport. The lining thickness is calibrated to provide wear resistance without compromising flexibility, allowing the material to adapt well to the interior surfaces of the trunk. [0008] In the prior art, trunk lining does not attach directly to the vehicle's rear seat, making it necessary to use additional coupling parts. The presence of these parts increases the complexity of the lining, the assembly time, and the material costs involved in manufacturing and assembly. Furthermore, the addition of these components does not contribute to the overall aesthetics of the compartment, making the trunk interior aesthetically unpleasant and detracting from the perceived quality of the finish. The lack of integration can also compromise space efficiency and protection against dirt and damage, negatively impacting the overall functionality of the cargo compartment. [0009] To meet the needs relating to trunk lining, the prior art documents JP2021507841A and CN104029616B propose the solutions discussed below. [0010] Document JP2021507841A discloses a vehicle trunk floor used in the luggage compartment or rear seat backrest, covering all or part of the visible sides of the trunk. The problem to be solved is the fragility and lack of wear resistance of traditional trunk floor surfaces, which, in addition to being easily damaged, do not have a good weight-to-rigidity ratio. The problems are solved by applying an elastic, flexible, and wear-resistant protective layer to a rigid support. This layer can be made of materials such as polyurethane, and the support can comprise a core of fiberglass-reinforced paper and rigid polyurethane foam. The structure improves wear resistance, reduces weight, and provides mechanical properties such as high tensile and rupture strength. JP2021507841A, however, does not disclose that the solution is used to ensure the fit and coupling of the trunk floor with the rear seat. An additional problem is that the solution revealed by the document does not facilitate the process of assembling the part in the vehicle. [0011] Document CN104029616B discloses a luggage securing and storage system for vehicles. The problem to be solved is the difficulty of maintaining security when storing luggage in the rear compartment of vehicles. Additional challenges include the difficulty in operating seat locking mechanisms and the lack of suitable systems for securely storing fragile items, such as laptops, within the trunk. The document aims to reduce the weight and volume of the rear seats using a pivoting lever mechanism that moves the seat back between the upright and folded positions. The
