Pivoting Seat Backrest as a Convertible Wind Deflector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convertible motor vehicles experience air draughts and whirlwinds inside the passenger compartment, especially at high speeds, due to the absence of a wind deflector, and the installation and storage of traditional wind deflectors are cumbersome and occupy valuable space.
Innovation Solution
A motor vehicle seat with a backrest portion that can pivot from a seated position to a wind deflector position, using a mechanism with a hinge and springs to automatically adjust and secure the position, thereby eliminating the need for a separate wind deflector and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate wind deflector is provided in the vehicle, then air turbulence is reduced, but device complexity and space occupation increase
Solution Approach 1:
The patent merges the wind deflector function with the seat backrest by making the backrest adjustable between a seated position and a wind deflector position. This integration eliminates the need for a separate wind deflector component, thereby reducing device complexity while maintaining the ability to reduce air turbulence when needed.
Solution Approach 2:
The seat backrest is designed to serve dual functions: providing seating support in normal operation and acting as a wind deflector when adjusted to the second position. This multi-functionality allows the same component to address air turbulence without requiring additional dedicated parts.
2Object-affected harmful factors
If a separate wind deflector is provided in the vehicle, then air turbulence is reduced, but the vehicle requires additional storage space
Solution Approach 1:
By integrating the wind deflector function into the existing seat backrest structure, the patent eliminates the need for a separate storage compartment that would be required for a detachable wind deflector. The space previously needed for storing a separate wind deflector is now freed up.
Solution Approach 2:
The multi-functional backrest that serves as both a seat support and wind deflector removes the requirement for additional storage space, as no separate wind deflector needs to be stored when not in use.
3Object-affected harmful factors
If a traditional wind deflector is used, then air turbulence is reduced, but installation and removal operations become cumbersome
Solution Approach 1:
The integration of the wind deflector function into the seat backrest eliminates the need for separate installation and removal operations. The backrest can be adjusted between positions using the existing seat adjustment mechanism, making the operation as simple as adjusting the seat itself.
Solution Approach 2:
The backrest is designed with dynamic adjustability, allowing it to be easily repositioned between the seated position and wind deflector position. This dynamic capability enables quick adaptation to different driving conditions without cumbersome installation or removal procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The seat effectively reduces air turbulence inside the vehicle by acting as a wind deflector at high speeds, while also simplifying the installation and storage process, and increasing passenger comfort and trunk space utilization.
Implementation Method 1
a mechanism (8) configured to couple the portion (6) to the portion (5) in a movable manner between a first and a second position
Implementation Method 2
using a mechanism with a hinge and springs to automatically adjust and secure the position
Implementation Method 3
the portion (6), in the second position, is tilted upwards relative to the horizontal direction... the portion (6), in the second position, is tilted upwards relative to the horizontal direction, more in particular at an acute angle

AI summary
A motor vehicle seat includes a backrest portion a first body, a second body and a mechanism configured to coupled the backrest portion to the first body in a movable manner between a first position, in which the backrest portion is arranged between the first and the second body, the latter defining a base extending crosswise to the backrest portion in order to support a passenger seating with the back resting against the backrest portion on a first surface of the backrest portion, and a second position, in which the backrest portion has a second surface opposite the first surface and facing the second body; wherein the first surface, in the second position of the backrest portion, defines a wind deflector.
