Vehicle Seat Striker Curved Bracket Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat strikers rely on reinforcing brackets for strength, which can lead to inefficiencies in load distribution and increased risk of shearing forces when subjected to bending deformations.
Innovation Solution
A striker design featuring a metal engagement pin with a mounting bracket that includes a covering portion and a curved load-receiving portion, formed as a single metal plate, which absorbs loads and reduces shearing forces by distributing them effectively across the pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcing bracket is added to enhance striker strength, then the strength is improved, but the device complexity increases
Solution Approach 1:
The patent combines the covering portion and curved portion into a single integrated mounting bracket structure. The covering portion that protects the engagement pin is merged with the curved load-receiving portion into one piece, eliminating the need for separate reinforcing brackets while maintaining structural strength and reducing component count.
Solution Approach 2:
The patent introduces a curved portion with specific geometric shape that receives loads in multiple directions. By designing the mounting bracket with curved geometry rather than flat rigid structures, the bracket can absorb loads through deformation in a controlled manner, enhancing strength without adding multiple reinforcing elements.
2Strength
If a reinforcing bracket is used to restrict bending deformation, then the strength is improved, but the shearing force on weld beads increases
Solution Approach 1:
The patent employs a curved portion that is curved in approximately a U-shape to receive loads acting on the engagement pin. This curved geometry allows the mounting bracket to absorb large loads through controlled deformation, reducing the shearing force transmitted to the weld beads that join the engagement pin to the mounting bracket.
3Strength
If the engagement pin is fixed rigidly to enhance strength, then the strength is improved, but the load distribution becomes inefficient
Solution Approach 1:
The patent transitions from a rigid fixed connection to a dynamic connection where the curved portion can deform elastically under load. The curved portion is designed to flex and absorb energy, allowing the system to adapt to varying load conditions and distribute forces more efficiently through the structure rather than concentrating them at rigid connection points.

Function Achieved in This Case
Enhances the strength of the striker by reducing shearing forces and allowing for more efficient load absorption, thereby improving the overall structural integrity without the need for additional reinforcing brackets.
Implementation Method 1
the curved portion is deformed to thereby absorb the load

AI summary
A striker applied to a vehicle seat includes an engagement pin having a bar shape and a mounting bracket. The mounting bracket includes: a covering portion that covers a part of a lateral surface of the engagement pin from outside and to which one end portion of the engagement pin along a longitudinal axis of the engagement pin is fixed; and a mounting portion that is mounted to a vehicle seat or a vehicle. When directions perpendicular to the longitudinal axis of the engagement pin are regarded as first directions and directions approximately corresponding to seat front-rear directions are regarded as second directions in a state where the mounting portion is mounted, the covering portion is provided with a first load receiving portion that is approximately perpendicular to the first directions and a second load receiving portion that is approximately perpendicular to the second directions.
