Car Seat Modular Headrest

Abstract

The invention relates to a novel modularized headrest of an automobile seat. The novel modularized headrest is characterized by comprising a platform body used as the base of the modularized headrest, wherein a cavity allowing a safety module system to be mounted, a wing-foundation fitting plane allowing a wing module system to be mounted, a frontward-backward slider channel, a lock-bolt fitting piece, slide rails for button return pieces, spring fixing claws for the button return pieces, upper-section fitting cavities of headrest rods, and a clamping transverse beam of an outer cover shell are arranged on the platform body, wherein the frontward-backward slider channel, the lock-bolt fitting piece, the slide rails and the spring fixing claws are used for allowing a frontward-backward sliding module system to be mounted; the upper-section fitting cavities are used for allowing a rotary regulation module system to be mounted; fixing bolt holes are formed in the lower ends of the upper-section fitting cavities; the clamping transverse beam is used for allowing the outer cover shell to be mounted. According to the novel structural design mode of the headrest provided by the invention, the headrest can be randomly matched with function modules according to demands of clients so as to satisfy the demands of the clients, repeated design is not needed, and each function module can be independently mounted on the platform body, so that the situation that no module is attached to the others in the headrest is guaranteed.

Description

technical field [0001] The invention relates to a novel automobile headrest. Specifically, it involves the design and development of functional units related to automotive headrests based on a relatively solid platform with modularization as the basic model, so as to realize a richer functional matrix of headrest products and satisfy customers' personalization to the greatest extent. Require. Background technique [0002] At present, in the design, development and production process of automobile headrests in the world, neither the modular design mode of functional units nor the platform design mode is adopted. The problem that exists is: on the one hand, mostly be at the demand of client, design has the headrest with different functions respectively. Car seat headrests usually require front and rear adjustment functions, left and right adjustment functions and safety functions. Therefore, for different headrests, the functional modules cannot be used in common and need to...

Problems solved by technology

The problem is that: on the one hand, most of the headrests with different functions are designed according to the needs of customers.

Car seat headrests usually require front and rear adjustment functions, left and right adjustment functions and safety functions. Therefore, for different headrests, the functional modules cannot be used in common and need to be designed separately, which not only increases design costs and wastes resources, but also often causes Complex product structure, repetitive design, long design development and verification cycle and other adverse design effects

On the other hand, part of the installation points of one functional unit often needs to be arranged on the parts of another functional unit, so that each functional unit cannot be independently installed with the headrest core

As a result, the installation of some functional units must be accompanied by other functional units, which cannot fully meet the individual requirements of customers.

For example, the safety blasting module of the car headrest is closely combined with the front and rear sliding modules. The front end of the safety blasting module is screwed and matched with the front and rear sliding modules in the form of a screw buckle. The technical installation process ensures the installation accuracy and installation strength of the safety blasting module. However, this will cause the screw fastening between the front screw buckle structure of the safety blasting module and the front and rear sliding modules, thus locking the front and rear of the headrest. The degree of freedom of sliding, only when the seat headrest is safely blasted, the headrest can move forward and backward, but in normal times, the front and rear movement of the headrest cannot be adjusted. Therefore, the front and rear adjustment function of the car seat headrest is lost.

Third, in the functional configuration of the existing car headrest, there is no precedent that can provide comfortable support for the customer's head by rotating up and down

Especially the comfort demands of some extreme groups cannot be fully satisfied

For example, the head of a very tall person and a very short person cannot be fully and effectively supported
