Vehicle Seat Spindle Gear Holder for Multi-Angle Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spindle drive arrangements for vehicle seats require multiple variants of gear holders for different electric motors and threaded spindles, leading to increased complexity and cost, and do not efficiently dissipate loads during vehicle collisions.
Innovation Solution
A gear arrangement with a gear holder having non-parallel receiving openings for fastening screws or pins, allowing it to be oriented in multiple ways, and a gear housing with connecting elements that can be rotated relative to the gear holder, enabling a core standard unit configuration that adapts to various motor and spindle variants, and dissipates loads through a worm gear and gear cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple variants of gear holders are used for different electric motors and threaded spindles, then the spindle drive arrangement can be adapted to different configurations, but the device complexity and number of parts increase
Solution Approach 1:
The gear holder is designed with multiple receiving openings arranged at different angles (e.g., 0°, 45°, 90°, 135°) relative to a reference direction, allowing a single gear holder design to accommodate multiple orientations of the gear housing. This universal design eliminates the need for multiple specialized gear holder variants, reducing part complexity while maintaining adaptability to different motor and spindle configurations
Solution Approach 2:
The gear housing is mounted on the gear holder in a rotatable manner, allowing dynamic adjustment of the gear housing orientation relative to the gear holder. This dynamic mounting enables the same gear holder to work with different motor and spindle variants by simply rotating the gear housing to the appropriate orientation, rather than requiring different rigid gear holder designs for each variant
2Strength
If the gear housing is fixed rigidly to the gear holder, then the connection is stable and strong, but the ability to adjust orientation and adapt to different variants is reduced
Solution Approach 1:
The gear housing is mounted on the gear holder in a rotatable manner rather than being rigidly fixed, enabling dynamic orientation adjustment. The gear housing can be rotated to different angles (e.g., 0°, 45°, 90°, 135°) to accommodate different motor and spindle configurations. Once the desired orientation is achieved, the position is secured, providing both adaptability and stable connection
3Device complexity
If traditional gear holder designs are used, then the structure is simple, but loads during vehicle collisions are not efficiently dissipated
Solution Approach 1:
The connection between the gear housing and gear holder is segmented into multiple discrete connection points through the use of multiple receiving openings with pins. This segmentation allows the load to be distributed across multiple connection points rather than concentrated at a single point, improving collision safety while maintaining structural simplicity
Solution Approach 2:
The receiving openings are arranged in multiple angular dimensions (0°, 45°, 90°, 135°) rather than being aligned in a single direction. This multi-dimensional arrangement provides load distribution paths in multiple directions, enhancing collision safety by dissipating forces from various angles while keeping the overall structure simple

AI summary
A gearing arrangement for a spindle drive arrangement may have a gearing housing and a gearing holder. The gearing holder may have at least two receiving openings, one for each fastening screw or one for each fastening bolt for fastening to another component, in particular to a vehicle seat. The at least two receiving openings may be oriented at right-angles and/or obliquely with respect to one another. A spindle drive arrangement having such a gearing arrangement, and also to a vehicle seat having such a spindle drive arrangement is also provided.
