Reverse Drive Recliner Assembly With Rear-Mounted Motor Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing and assembly of motor-powered recliners are complicated by the need to thread and secure wiring for front-mounted motors, which increases time and risk of damage, and the exposed motor is aesthetically unpleasing and vulnerable to damage.
Innovation Solution
A power mechanism with a rear-mounted motor and reverse drive assembly, where the motor is positioned at the end of a horizontal track proximate to the rear of the recliner, allowing direct wiring attachment and reducing visibility and vulnerability, with reverse transfer linkages that shorten the horizontal track length for clearance and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor is mounted at the front of the recliner, then the motor has clearance from the seat box edges, but the wiring must be threaded through multiple linkages increasing manufacturing complexity and time
Solution Approach 1:
The motor is relocated from the front of the recliner to the rear, reversing the conventional mounting position. This inversion allows the power plug to be positioned at the rear near the motor, eliminating the need to thread wiring through multiple linkages and significantly reducing manufacturing complexity while maintaining adequate clearance through the reversed configuration
2Ease of manufacture
If the motor is mounted at the front of the recliner, then the horizontal track can be positioned beneath the seat box, but the exposed motor is aesthetically unpleasing and vulnerable to damage
Solution Approach 1:
The motor mounting position is inverted from front to rear, placing the motor in a more protected location. The rear mounting position provides aesthetic advantages by hiding the motor from front views and reduces vulnerability to damage from foot traffic and objects, while the horizontal track positioning beneath the seat box is maintained through the reversed configuration

AI summary
A reverse drive assembly for recliner in which a motor is mounted at the end of the horizontal track, proximate to the rear of the recliner. A traveler assembly having a reverse transfer linkage having a greater bend is positioned along the track forward of the motor, wherein the traveler assembly actuates extension of an ottoman assembly and the reclining of a seat back.
