Description

本発明は、車輌のヘッドレストサポート（以下、サポートとする）に関する。 The present invention relates to a vehicle headrest support (hereinafter referred to as support).

このサポートとヘッドレストステー（以下、ステーとする）及びブラケットの相互間に発生するガタ防止を、図るために、本出願人は、幾多の出願（発明）をした。その発明の中で、複数が、製品化されている。 In order to prevent backlash occurring between the support, the headrest stay (hereinafter referred to as a stay) and the bracket, the applicant has filed a number of applications (inventions). In the invention, a plurality are commercialized.

しかし、昨今のユーザからの要望と、社会情勢から、更なるガタ防止が要望されている。この要望に応えるために、既に、出願済である。例えば、特願２０１３−２３０８４８号である。 However, further backlash prevention is demanded from the recent demand from users and the social situation. In order to meet this demand, an application has already been filed. For example, Japanese Patent Application No. 2013-230848.

今回の出願は、先願の改良であり、かつ下記の文献（１）の改良である。 This application is an improvement of the prior application and an improvement of the following document (1).

文献（１）は、特開２０１２−２１８４５８号公報に記載された、通常時において、シート共振の改善のため、バネ定数を低減しても、後突時には、ムチ打ち症を抑制できるバネ定数の増大が図れる自動車用ヘッドレスト支持装置を提案する。構成は、自動車用ヘッドレスト支持装置において、サポートとブラケット（ヘッドレストブラケット）との間、ステー挿通孔（ヘッドレストステー挿通孔）のステーとサポートとの間、又はステー挿通孔のステーとブラケットとの間、の少なくとも、何れかの１つの部位に、ブラケットの上下方向端部に対応する部位で車輌前後方向部位に、ダイラタント特性を有する可撓性部材（バネ、バネ素材等）を配置した構造である。しかしながら、この発明は、ヘッドレストの振動防止に留まっていると考えられる。 Document (1) is disclosed in Japanese Patent Application Laid-Open No. 2012-218458. In the normal state, even if the spring constant is reduced to improve seat resonance, the spring constant that can suppress whiplash at the time of rear collision is described. An automobile headrest support device that can be increased is proposed. In the headrest support device for an automobile, the configuration is between the support and the bracket (headrest bracket), between the stay and the support of the stay insertion hole (headrest stay insertion hole), or between the stay and the bracket of the stay insertion hole, This is a structure in which a flexible member (spring, spring material, etc.) having a dilatant characteristic is disposed in at least one of the portions corresponding to the vertical end portion of the bracket and in the vehicle longitudinal direction portion. However, it is considered that the present invention is limited to preventing vibration of the headrest.

特開２０１２−２１８４５８号公報JP 2012-218458 A

少なくとも、文献（１）では、ステーとサポート、並びにブラケットとの公差等で発生する問題点、即ち、車内の静寂確保、快適性確保とか、サポートの共振効果による静寂化、快適化、並びに自励振動による減衰、等に関しては、十分とは考えられない。 At least in Reference (1), there are problems that occur due to tolerances between the stay, support, and bracket, ie, quietness in the vehicle, ensuring comfort, quietness, comfort, and self-excited by the resonance effect of the support. It is not considered sufficient for damping due to vibration.

上記に鑑み、本発明は、従来のサポートに、構造的な技術と工夫を行うことで、ステーとサポートとで発生するガタ／共振防止効果を達成し、もって、車内の静寂確保、快適性確保、を図り、かつ自励振動によるガタと振動減衰を図ることを意図する。また、サポートの胴体（本体部）の傾斜化でブラケットへの抜差し（挿入と、脱外）容易化と、ブラケットとの相性の向上化を図ることを意図する。 In view of the above, the present invention achieves the effect of preventing rattling / resonance generated by the stay and the support by structural technology and ingenuity to the conventional support, thereby ensuring quietness and comfort in the vehicle. This is intended to reduce vibrations and vibrations due to self-excited vibration. Further, it is intended to facilitate the insertion / extraction (insertion and removal) from the bracket and to improve the compatibility with the bracket by inclining the support body (main body portion).
