Description

本発明は、座席ユニット内に組み込まれた電装品をスイッチ操作により制御する装置に関するものである。   The present invention relates to an apparatus for controlling an electrical component incorporated in a seat unit by a switch operation.

近年、自動車などの車両に関する技術の発展に伴い、車両用座席ユニットにおいても、例えば前後スライドやリクライニングなどを電動で行うなど、高機能化が進展している。このため座席ユニット内には、各種電装品への電力供給や制御信号伝送を行うための多数の電線が配線される（特許文献１）。   In recent years, along with the development of technologies related to vehicles such as automobiles, higher functionality has also been developed in vehicle seat units, for example, by performing front and rear slides and reclinings electrically. For this reason, in the seat unit, many electric wires for supplying power to various electrical components and transmitting control signals are wired (Patent Document 1).

また最近では、車両ユーザーの好みの高級化により、背もたれ部内にも、温度調節器、ランバー制御用モーター、ヘッドレスト制御用モーターなどの電装品が組み込まれるようになってきている。   In recent years, electrical components such as a temperature controller, a lumbar control motor, and a headrest control motor have come to be incorporated into the backrest due to the high-grade preference of vehicle users.

このような座席ユニット内に設けられたモーターなどの電装品の制御を行うため、従来は電装品毎に制御部が設けられていた。またクッション部の側面には、それぞれの電装品を操作するスイッチが設けられ、それぞれの制御部はこのスイッチからの信号に応じて電装品を動作させていた。   In order to control electrical components such as a motor provided in such a seat unit, a control unit has been conventionally provided for each electrical component. Further, switches for operating the respective electrical components are provided on the side surfaces of the cushion portion, and the respective control units operate the electrical components in response to signals from the switches.

特開平１１−１８８６２号公報Japanese Patent Laid-Open No. 11-18862

従来の電装品制御方式では、背もたれ部内の電装品が増えると、それに応じてクッション部側から背もたれ部側へ渡る電線の本数も多くなる。一方、クッション部と背もたれ部の間は電線の配索スペースが狭いため、クッション部側から背もたれ部側へ渡る電線の本数が増えると、背もたれ部をリクライニングさせるとき等に、電線が相互にこすれ合って、電線の被覆が劣化する懸念がある。また電線相互の摩擦が大きくなると、個々の電線の動きの自由度が低くなるため、背もたれ部をリクライニングさせるとき等に、電線が引きつって電線の端末部に余分な応力が加わる懸念がある。   In the conventional electrical component control system, when the electrical components in the backrest portion increase, the number of wires extending from the cushion portion side to the backrest portion side increases accordingly. On the other hand, since the wiring space between the cushion part and the backrest part is narrow, if the number of wires extending from the cushion part side to the backrest part side increases, the wires rub against each other when reclining the backrest part, etc. Therefore, there is a concern that the covering of the electric wire deteriorates. Further, when the friction between the wires increases, the degree of freedom of movement of the individual wires decreases, and there is a concern that extra stress may be applied to the end portions of the wires when the backrest portion is reclined.

本発明の目的は、クッション部側から背もたれ部側へ渡る電線の摩擦の問題を低減すると共に、上記電線の端末部に余分な応力がかかるおそれのない座席ユニットの電装品制御装置を提供することにある。   An object of the present invention is to provide a seat unit electrical component control device that reduces the problem of electric wire friction from the cushion portion side to the backrest portion side and that does not cause excessive stress to be applied to the terminal portion of the electric wire. It is in.

本発明に係る座席ユニットの電装品制御装置は、

前記背もたれ部内には、前記第一の統合制御部から制御信号を受信して、その制御信号により宛先の電装品を制御する第二の統合制御部を設け、
前記制御信号発生部と第一の統合制御部との間並びに第一の統合制御部と第二の統合制御部との間を、多重化された制御信号と電力を伝送する電線で接続した、
ことを特徴とするものである。 An electrical component control device for a seat unit according to the present invention is:
In a seat unit comprising a plurality of electrical components incorporated under the cushion portion, a plurality of electrical components incorporated in the backrest portion, and a switch assembly that operates these electrical components,
In the switch assembly unit, a control signal generation unit that multiplexes and transmits the control signal generated by each switch so that it can be identified which control signal is addressed to the electrical component,
Under the cushion part, when the control signal received from the control signal generation part is addressed to an electrical component incorporated under the cushion part, the destination electrical component is controlled by the control signal, If it is destined for the electrical components incorporated in the backrest part, provide a first integrated control part that transfers the control signal to the backrest part side,
In the backrest part, a control signal is received from the first integrated control part, and a second integrated control part for controlling a destination electrical component by the control signal is provided,
Between the control signal generation unit and the first integrated control unit and between the first integrated control unit and the second integrated control unit are connected by multiplexed control signals and electric wires that transmit power,
It is characterized by this.

また本発明に係る座席ユニットの電装品制御装置は、
クッション部の下に組み込まれた複数の電装品と、背もたれ部内に組み込まれた複数の電装品と、これらの電装品を操作するスイッチ集合部とを備えた座席ユニットにおいて、
前記クッション部の下には、前記スイッチ集合部から受信した制御信号が、クッション部の下に組み込まれた電装品を制御するものである場合は、その制御信号により宛先の電装品を制御し、背もたれ部内に組み込まれた電装品を制御するものである場合は、その制御信号をどの電装品宛の制御信号かを識別できるように多重化して背もたれ部側に送信する第一の統合制御部を設け、
前記背もたれ部内には、前記第一の統合制御部から制御信号を受信して、その制御信号により宛先の電装品を制御する第二の統合制御部を設け、
前記第一の統合制御部と第二の統合制御部との間を、多重化された制御信号と電力を伝送する電線で接続した、
構成とすることもできる。 In addition, the electrical equipment control device for a seat unit according to the present invention includes:
In a seat unit comprising a plurality of electrical components incorporated under the cushion portion, a plurality of electrical components incorporated in the backrest portion, and a switch assembly that operates these electrical components,
Under the cushion part, if the control signal received from the switch assembly part is to control the electrical component incorporated under the cushion part, the control electrical signal is controlled by the control signal, In the case of controlling an electrical component incorporated in the backrest, a first integrated control unit that multiplexes the control signal so that it can be identified to which electrical component is transmitted and transmits it to the backrest side. Provided,
In the backrest part, a control signal is received from the first integrated control part, and a second integrated control part for controlling a destination electrical component by the control signal is provided,
Between the first integrated control unit and the second integrated control unit, connected by a multiplexed control signal and an electric wire for transmitting power,
It can also be configured.

本発明によれば、電装品の制御信号を多重化して伝送するので、クッション部側から背もたれ部側へ渡る電線の本数を従来よりも大幅に少なくできる（基本的には背もたれ部内の電装品の数にかかわらず３本にできる）。このため、背もたれ部のリクライニングなどにより、クッション部と背もたれ部とが相対的に移動しても、電線相互のこすれ合いは軽度のものとなり、電線の引きつりも生じなくなる。したがって電線被覆が劣化するおそれが少なくなると共に、電線端末部に余分な応力が加わるのを防止できる。   According to the present invention, since the control signals of the electrical components are multiplexed and transmitted, the number of wires extending from the cushion portion side to the backrest portion side can be greatly reduced compared to the conventional case (basically, the electrical components in the backrest portion Can be 3 regardless of the number). For this reason, even if the cushion portion and the backrest portion move relative to each other by reclining the backrest portion or the like, the rubbing between the electric wires becomes light and the electric wires are not pulled. Therefore, the possibility that the wire coating is deteriorated is reduced, and it is possible to prevent an excessive stress from being applied to the wire terminal portion.

本発明の実施形態の説明に入る前に、座席ユニットに組み込まれる電装品の配置と、本発明者等が先に検討したワイヤーハーネス配索構造について、図４ないし図６を参照して説明する。図４において、１０は車両用座席ユニット、１２はクッション部、１４は背もたれ部、１６はスライド制御用モーター、１８はクッション長制御用モーター、２０はフロントバーチカル（クッション前部高さ）制御用モーター、２２はリフター（クッション高さ）制御用モーター、２４はクッション部温度調節用ペルチエクーラー、２６は送風ファン、２８は背もたれ部温度調節用ペルチエクーラー、３０はランバー制御用モーター、３２はリクライニング制御用モーター、３４は照明ランプ、３６はヘッドレスト制御用モーター、３８はこれらの電装品を動作させるためのスイッチを集めたスイッチ集合部である。これらの電装品への電力供給や信号伝送を行うため、座席ユニット１０内にはワイヤーハーネス４０が配索される。なお４２はワイヤーハーネス４０の電線束集合部を収容する保護ケースである。   Prior to the description of the embodiment of the present invention, the arrangement of the electrical components incorporated in the seat unit and the wire harness wiring structure previously examined by the present inventors will be described with reference to FIGS. . In FIG. 4, 10 is a vehicle seat unit, 12 is a cushion portion, 14 is a backrest portion, 16 is a slide control motor, 18 is a cushion length control motor, and 20 is a front vertical (cushion front height) control motor. , 22 is a lifter (cushion height) control motor, 24 is a cushion temperature control peltier, 26 is a blower fan, 28 is a backrest temperature control peltier, 30 is a lumbar control motor, and 32 is a reclining control. A motor, 34 is an illumination lamp, 36 is a headrest control motor, and 38 is a switch assembly that collects switches for operating these electrical components. In order to perform power supply and signal transmission to these electrical components, a wire harness 40 is routed in the seat unit 10. Reference numeral 42 denotes a protective case for accommodating the wire bundle collecting portion of the wire harness 40.

図５はワイヤーハーネス４０の配線系統図である。図５において、図４と同一部分には同一符号を付してある。４４は温度調節用回路基板で、クッション部１２の温度調節を行うペルチエクーラー２４及び送風ファン２６と、背もたれ部温度調節用ペルチエクーラー２８の制御を行うものである。この温度調節用回路基板４４は保護ケース４２に収容されている。３８ａはランバー制御用モーター３０を作動させるスイッチ、３８ｂはクッション長制御用モーター１８を作動させるスイッチ、３８ｃはそれ以外のモーターを作動されるスイッチ集合部、４６は車体フロア側の配線に接続されるコネクタである。車体フロア側の配線からはこのコネクタ４６を介して電力及び温度調節等に必要な制御信号が供給される。   FIG. 5 is a wiring system diagram of the wire harness 40. 5, the same parts as those in FIG. 4 are denoted by the same reference numerals. Reference numeral 44 denotes a temperature adjustment circuit board which controls the Peltier cooler 24 and the blower fan 26 for adjusting the temperature of the cushion portion 12 and the Peltier cooler 28 for adjusting the backrest temperature. The temperature adjusting circuit board 44 is accommodated in the protective case 42. 38a is a switch for operating the lumbar control motor 30, 38b is a switch for operating the cushion length control motor 18, 38c is a switch assembly for operating other motors, and 46 is connected to wiring on the vehicle body floor side. It is a connector. Control signals necessary for power and temperature adjustment are supplied from the wiring on the vehicle body floor side through this connector 46.

図６はワイヤーハーネス４０のさらに詳細な配線図である。図６において、図５と同一部分には同一符号を付してある。なお符号１６Ｃ〜３６Ｃはそれぞれ、図４及び図５に示す電装品１６〜３６に接続されるコネクタである。また４８は保護ケース４２内の電線を整理する布線プレート、４４は布線プレート４８に搭載された温度調節用回路基板、５０はワイヤーハーネス４０の配索経路を規定するダクトである。   FIG. 6 is a more detailed wiring diagram of the wire harness 40. In FIG. 6, the same parts as those in FIG. Reference numerals 16C to 36C denote connectors connected to the electrical components 16 to 36 shown in FIGS. Reference numeral 48 denotes a wiring plate for arranging the electric wires in the protective case 42, 44 denotes a temperature control circuit board mounted on the wiring plate 48, and 50 denotes a duct for defining a wiring route of the wire harness 40.

図４ないし図６に示すワイヤーハーネス配索構造は、個々の電装品とスイッチを１対１で対応させて電線でつなぐ方式であるため、電装品の数が増えると電線の本数も増えることになる。その結果、図５及び図６から明らかなように、ワイヤーハーネス４０の、クッション部１２側から背もたれ部１４側に渡る部分４０ｐと、スイッチ集合部３８につながる部分４０ｑで、電線の本数が非常に多くなってしまう。ワイヤーハーネス４０の渡り部分４０ｐの電線本数が多くなると、背もたれ部をリクライニングさせるとき等に、電線相互の摩擦による損傷が発生しやすい。またワイヤーハーネス４０のスイッチにつながる部分４０ｑの電線本数が多くなると、電線束の剛性が増すため、クッション部１２の下の狭い空間での配索が困難になる。本発明はこのような課題を解決するものである。   The wire harness routing structure shown in FIGS. 4 to 6 is a system in which individual electrical components and switches are associated with each other in a one-to-one correspondence, so that the number of electrical components increases as the number of electrical components increases. Become. As a result, as apparent from FIGS. 5 and 6, the number of wires in the wire harness 40 is very large in the portion 40 p extending from the cushion portion 12 side to the backrest portion 14 side and the portion 40 q connected to the switch assembly portion 38. It will increase. When the number of wires in the crossover portion 40p of the wire harness 40 is increased, damage due to friction between the wires is likely to occur when the backrest portion is reclined. Moreover, since the rigidity of an electric wire bundle will increase when the number of the electric wires of the part 40q connected to the switch of the wire harness 40 increases, the wiring in the narrow space under the cushion part 12 becomes difficult. The present invention solves such problems.

図１及び図２は本発明の一実施形態を示す。図１及び図２において、図４ないし図６と同一部分には同一符号を付してある。この実施形態では、座席ユニット１０内に組み込まれた電装品を作動させるためのスイッチ（スライドスイッチ、リクライニングスイッチ、リフタースイッチ、フロントバーチカルスイッチ、クッションスイッチ、ヘッドレストスイッチ、ランバースイッチ等）をまとめたスイッチ集合部３８に、それぞれのスイッチから出た制御信号を共通の電線で送信できるようにする制御信号発生部５２が設けられる。この制御信号発生部５２（ＥＣＵは電子制御ユニットの略、以下同じ）は、それぞれのスイッチから出た制御信号に宛先（アドレス）を付し、その制御信号がどの電装品宛のものかを識別できるようにして（多重化して）送信するものである。   1 and 2 show an embodiment of the present invention. 1 and 2, the same parts as those in FIGS. 4 to 6 are denoted by the same reference numerals. In this embodiment, a switch set in which switches (slide switch, reclining switch, lifter switch, front vertical switch, cushion switch, headrest switch, lumbar switch, etc.) for operating electrical components incorporated in the seat unit 10 are collected. The unit 38 is provided with a control signal generation unit 52 that allows the control signal output from each switch to be transmitted using a common wire. This control signal generator 52 (ECU is an abbreviation of an electronic control unit, hereinafter the same) attaches a destination (address) to the control signal output from each switch, and identifies which electrical component the control signal is directed to. It is transmitted (multiplexed) as possible.

またクッション部１２の下には第一の統合制御部５４が設けられ、背もたれ部１４内には第二の統合制御部５６が設けられる。なお図２において、５８は第一の統合制御部５４に付随するメモリー回路基板である。   A first integrated control unit 54 is provided below the cushion portion 12, and a second integrated control unit 56 is provided in the backrest portion 14. In FIG. 2, reference numeral 58 denotes a memory circuit board attached to the first integrated control unit 54.

第一の統合制御部５４は、制御信号発生部５２から受信した制御信号が、クッション部の下に組み込まれた電装品（スライド制御用モーター１６等）宛のものである場合は、その制御信号により宛先の電装品を制御し、背もたれ部１４内に組み込まれた電装品（ランバー制御用モーター３０等）宛のものである場合は、その制御信号を背もたれ部１４側の第二の統合制御部５６に転送するものである。   If the control signal received from the control signal generator 52 is addressed to an electrical component (such as the slide control motor 16) incorporated under the cushion, the first integrated controller 54 controls the control signal. If the destination electrical component is addressed to an electrical component (such as the lumbar control motor 30) incorporated in the backrest portion 14, the control signal is sent to the second integrated control portion on the backrest portion 14 side. 56.

第二の統合制御部５６は、第一の統合制御部５４から制御信号を受信して、その制御信号により宛先の電装品を制御するものである。   The second integrated control unit 56 receives a control signal from the first integrated control unit 54 and controls a destination electrical component by the control signal.

このようにすると、第一の統合制御部５４及び第二の統合制御部５６で、各電装品宛の制御信号及び供給電力の振り分けができるため、制御信号発生部５２と第一の統合制御部５４の間の電線並びに第一の統合制御部５４と第二の統合制御部５６との間の電線は、電力伝送線１本と、信号伝送線１本と、アース線１本の、合計３本で済むことになる。したがってワイヤーハーネス４０の、クッション部１２側から背もたれ部１４側に渡る部分４０ｐでは、電線相互の摩擦による問題が解消される。また制御信号発生部５２と第一の統合制御部５４をつなぐ部分４０ｑでも、クッション部１２の下の狭い空間での配索を容易に行うことができる。   In this way, since the first integrated control unit 54 and the second integrated control unit 56 can distribute the control signal and supply power addressed to each electrical component, the control signal generating unit 52 and the first integrated control unit The electric wires between 54 and the electric wires between the first integrated control unit 54 and the second integrated control unit 56 are a total of three power transmission lines, one signal transmission line, and one ground wire. A book will suffice. Therefore, in the portion 40p of the wire harness 40 extending from the cushion portion 12 side to the backrest portion 14 side, the problem due to the friction between the electric wires is solved. In addition, even in the portion 40q that connects the control signal generation unit 52 and the first integrated control unit 54, it is possible to easily perform routing in a narrow space below the cushion portion 12.

図３は本発明の他の実施形態を示す。この実施形態が前記実施形態と異なる点は、各電装品を制御するスイッチの部分は図５と同様なスイッチ集合部３８とし、このスイッチ集合部３８と第一の統合制御部５４との間も図５と同じ本数の電線で接続したものである。それ以外の構成は前記実施形態と同じであるので、同一部分には同一符号を付してある。この実施形態では、スイッチ集合部３８につながる部分の電線の本数は図５の場合と同様であるが、ワイヤーハーネス４０のクッション部１２側から背もたれ部１４側に渡る部分４０ｐでは、電線本数が少なくなり、電線相互の摩擦による問題が解消される。   FIG. 3 shows another embodiment of the present invention. This embodiment is different from the above-described embodiment in that a switch portion for controlling each electrical component is a switch assembly portion 38 similar to that in FIG. 5, and between the switch assembly portion 38 and the first integrated control portion 54. They are connected by the same number of wires as in FIG. Since the other configuration is the same as that of the above-described embodiment, the same parts are denoted by the same reference numerals. In this embodiment, the number of wires in the portion connected to the switch assembly portion 38 is the same as in FIG. 5, but the number of wires is small in the portion 40p extending from the cushion portion 12 side to the backrest portion 14 side of the wire harness 40. Thus, the problem due to the friction between the wires is solved.
