BRIDE A.i.R. Bucket Seat

The BRIDE A.i.R. is a fixed full bucket seat designed around a new stream design concept, drawing its visual and structural inspiration from the aerodynamic flow of air through a two-seater vehicle. Developed as what BRIDE describes as a 3D aero device, the A.i.R. moves away from conventional bucket seat geometry and introduces a more dynamic, flowing form that is as much a design statement as it is a functional seat. The structural centerpiece of the A.i.R. is the semi-monocoque construction applied to the hip section. By integrating a semi-monocoque structure at this area, BRIDE significantly increased the rigidity of the seatback without adding the weight that conventional reinforcement methods would require. This approach, borrowed from aerospace and motorsport chassis engineering, allows the seat to achieve a stiffer, more stable platform for the driver while keeping the overall weight at 6.8kg across the FRP silver shell. The BRIDE patented LOWMAX system is incorporated into the A.i.R., delivering the low mounting position and optimized eye point that the system provides across the BRIDE lineup. Combined with a newly designed formula driving position, the seat places the driver at the correct height and angle for precise vehicle control, making it well suited to two-seater sports cars and performance-focused builds where driving position directly affects car feel and response.

Utilizing The LOWMAX System To Enable The Ultimate Low Driving Position

• Because A.i.R. utilizes the LOMAX system, a patented technology of BRIDE, it enables low positions even when seat space is tight. Even if the center of the steering and seat become offset, the LOWMAX system allows you to zero the offset. (With some car models it may not be zeroed)

A Characteristic Stream Design Inspired By The Flow of Air

• A.i.R. realizes extremely fine lines using a 3D design method. Especially the line from the belt hole onto the head rest required several prototypes before creating the final product. Designing for shell production requires a great deal of time and effort, but the intrepidness which is not found in traditional model designs is what makes the new genre full-bucket seat A.i.R. special.

Increased Seat Back Rigidity Through A Semi-Monocoque Hip-Side

• The shell of A.i.R.’s hip side part adopts a semi-monocoque structure. The increased shell rigidity of the seatback overall has increased the holding performance when driving. The increased rigidity around the lower back has also improved pedal operability with lateral Gs during high speed cornering.

Head Clearance Secured Even For Tall Drivers

• The A.i.R. seat surface is a large convex egg shape. Positioning the seat rail as if to insert this protrusion enables low positioning, ensuring enough head clearance even for tall drivers. This technology is BRIDE’s patented “LOMAX System” technology which realizes a low position even with tight seat spaces.

Fixed Bucket Seat With A Stream Design For A 2-Seater Utilizing A Newly Designed Formula Driving Position and The LOWMAX System

• A.i.R. is a “3D aero device” inspired by the flow of air in a 2-seater car, and a model created with a “new stream design” to produce more intrepidness. By adopting a semi-monocoque structure for the hip side, they have increased the rigidity of the seat back.
• Utilizing an FRP silver shell seat, it is finished with an extremely light weight of 6.8kg.

More Head Clearance Secured By Adopting The LOWMAX System

• The newly designed formula driving position and the adoption of the LOWMAX system secures more ceiling clearance, allowing them to provide seat positions perfect for even tall drivers.

Frequently Asked Questions

• What is the stream design concept behind the A.i.R.? The BRIDE A.i.R. is described as a 3D aero device, a seat whose form is inspired by the flow of air through a two-seater vehicle. The stream design moves away from the conventional bucket seat silhouette, producing a more dynamic and flowing visual profile while also informing the structural approach of the seat. The result is a seat that reads as more intrepid and purposeful in the cockpit of a two-seater compared to a traditionally shaped full bucket.
• What is the semi-monocoque structure and why is it used on the hip section? A semi-monocoque structure is a construction method where the outer shell itself carries and distributes structural loads rather than relying entirely on an internal frame. On the A.i.R., BRIDE applied this approach to the hip section of the seat to increase the rigidity of the seatback significantly without adding the weight that conventional reinforcement would introduce. It is the same principle used in aerospace and motorsport chassis design, adapted here to produce a stiffer, more stable seat platform at a weight of 6.8kg.
• What is the LOWMAX system and how does it benefit the A.i.R.? The LOWMAX system is a BRIDE-patented feature that achieves a lower mounting position than conventional full bucket seats allow. On the A.i.R., it works alongside the newly designed formula driving position to place the driver’s eye point and posture at the ideal height for control and spatial awareness in a two-seater cockpit. For sports car applications where headroom and driving position are closely related to car feel, the low seat height the LOWMAX system provides is a direct performance benefit.
• What shell material and weight does the A.i.R. use? The BRIDE A.i.R. uses an FRP silver shell and weighs 6.8kg. The lightweight figure is achieved through the combination of the FRP construction and the semi-monocoque hip structure, which improves rigidity without requiring heavier reinforcement materials or additional structural components.
• What type of vehicle is the A.i.R. designed for? The A.i.R. is designed specifically with two-seater vehicles in mind. The stream design concept, formula driving position, and LOWMAX system are all oriented toward the cockpit environment and driving dynamics of a two-seater sports car. It is suited to performance-focused builds where driving position, weight, and seatback rigidity are meaningful considerations.
• How does the A.i.R. differ from other BRIDE full bucket seats like the ZIEG IV? The ZIEG IV is built around a deep hold shell with a rounded backrest line developed primarily from circuit and competition feedback, with a focus on lateral G-force support and holdability across a wide range of driving environments. The A.i.R. takes a different approach, using the stream design concept and semi-monocoque hip structure to create a seat that is more specifically oriented toward the two-seater sports car cockpit, with the formula driving position and 3D aero design as its defining characteristics. Both use the LOWMAX system for low seat positioning, but the overall geometry, weight, and design intent of the two seats serve different driver and vehicle profiles.
