A recently granted patent (Publication Number: US11772772B2) describes an aircraft personal service unit configuration. The configuration includes a personal service unit, a bulkhead, and a transition end cap. The transition end cap is attached to the bulkhead and has a protrusion that extends behind the end of the personal service unit. The attachment end and the protrusion of the transition end cap form an L-shaped angle bracket. A soft seal element is located at the end of the protrusion and is used to bias the transition end cap against the personal service unit. The protrusion of the transition end cap and the personal service unit are designed to slide against each other.

In claim 2, it is specified that the soft seal element comprises a flexible material. This indicates that the seal element is made of a material that can bend or stretch, allowing it to conform to the shape of the transition end cap and provide a secure seal against the personal service unit.

This aircraft personal service unit configuration has potential applications in the aviation industry. The personal service unit refers to a compartment or area in an aircraft where passengers can access amenities such as food and beverages, entertainment systems, and other services. The configuration described in the patent aims to improve the sealing between the transition end cap and the personal service unit.

By using a soft seal element made of a flexible material, the transition end cap can be securely and tightly sealed against the personal service unit. This helps to prevent any leakage or loss of pressure between the two components. The sliding engagement between the protrusion of the transition end cap and the personal service unit allows for smooth movement and easy access to the personal service unit.

Overall, this patented aircraft personal service unit configuration offers a solution for improving the sealing and functionality of personal service units in aircraft. The use of a flexible soft seal element and the L-shaped angle bracket design of the transition end cap contribute to a more efficient and effective configuration.
