Rear Split Seat Collision Locking for Seatback Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear split seats in vehicles suffer from weak rigidity at the interface between the left and right seats, leading to potential deformation during collisions, which can result in passenger injury and damage to seatbelt anchors.
Innovation Solution
A collision locking device is introduced, featuring a striker structure on one seatback and a locking device on the other, which couples the seatbacks together via a locking operation triggered by inertial force during a collision, preventing deformation and maintaining the seats' original position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the left seat and right seat are connected only by a center hinge assembly, then the seat structure remains simple and easy to manufacture, but the rigidity of the interface between seats is weak
Solution Approach 1:
The locking device is activated in advance by inertial force generated during collision to couple the seatbacks together before deformation occurs, preventing harmful effects rather than correcting them after the fact
Solution Approach 2:
A striker structure is introduced as an intermediary component that mediates the coupling between left and right seatbacks during collision, enabling the locking mechanism to engage effectively
2Reliability
If the seatbacks are not coupled during collision, then the device complexity remains low, but the seatbacks deform easily under impact force
Solution Approach 1:
The locking device utilizes the inertial force generated during collision itself to activate the locking mechanism, making the system self-activating without requiring external sensors or control systems
Solution Approach 2:
The inertial force generated during collision, which would otherwise cause deformation and injury, is converted into a beneficial force that activates the locking mechanism to couple the seatbacks together
3Reliability
If the seatbelt anchor is mounted on the seatback, then the seatbelt function is integrated, but the anchor is damaged when the seatback deforms during collision
Solution Approach 1:
The locking device performs preliminary action by coupling the seatbacks together before the collision impact can cause deformation, thereby preventing damage to the seatbelt anchor and other components
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 device effectively prevents seatback deformation and reduces passenger injury by coupling the seatbacks together, thereby safeguarding passengers and preventing seatbelt anchor damage during collisions.
Implementation Method 1
a locking device mounted on the seatback of the left seat or the seatback of the right seat and operated so as to be locked and coupled to the striker structure by inertial force resulting from vehicle collision
