Purpose and function in the bodywork

This rear left window aperture seal strip has been designed specifically for the Seat Arona KJ7 model, taking into account the door geometry and factory mounting points. The component operates at the contact zone between the window and the door frame, where it is responsible for:

• limiting the ingress of water and contaminants into the door interior,
• reducing wind noise in the rear cabin area,
• stabilizing the window edge during opening and closing,
• protecting the paint on the frame edge against abrasion.

Thanks to its fitment for a specific location on the vehicle (rear, left side), the component works in harmony with the factory window lifting mechanism and other door seals.

Construction and technical properties

The window aperture seal strip utilizes an aluminium profile, which ensures adequate rigidity and shape stability along the entire door edge. This construction allows for:

• maintaining a constant contact line with the window along its entire length,
• limiting deformation during repeated opening and closing of the door,
• secure seating in the factory mounting points in the rear doors.

The component belongs to the Protective and decorative strips group, which means that apart from its sealing function, it also plays an aesthetic role – it visually organizes the window line and door edge, maintaining consistency with other body strips in the Arona model.

Benefits of using an original seal

Using an original window aperture seal strip in the rear left part of the body allows for maintaining the factory operating parameters of the door and window. Key advantages include:

• precise fit to the shape of the door and window in the Arona KJ7 model,
• visual consistency with other trim elements of the side body section,
• reduction of the risk of rattles, play, and leaks characteristic of poorly fitted replacements,
• maintaining the correct operation of the window lifting mechanism in the rear left part of the vehicle.

The component in used condition allows for an economical repair without compromising the original design and geometry intended by the manufacturer.

Installation zone – rear left in Seat Arona KJ7

The seal is intended for installation in the rear left body zone, within the door window frame. When correctly installed, it works with:

• the outer surface of the side window,
• the edge of the rear left door frame,
• other seals and protective strips in this part of the vehicle.

Such placement is significant for interior acoustics, protection against water, and the durability of the paint on the door edges, especially during daily urban use.
