Description

本発明は、ドライバーが誤ってアクセルペダルを踏み込んでしまう操作である誤踏み操作を防止するに好適な車両用シートに関する。 The present invention relates to a vehicle seat suitable for preventing an erroneous depressing operation, which is an operation in which a driver accidentally depresses the accelerator pedal.

従来、ドライバーが誤ってアクセルペダルを踏み込んでしまう誤踏み操作により、車両が急発進してしまうことを防止するために、車両に誤踏み対応装置を装備する技術が知られいる。例えば、特許文献１に記載の誤踏み対応装置は、誤踏み操作を検出する誤踏み操作検出手段と、誤踏み操作が検出された場合に、駆動力を制限する制御である駆動力制限制御を実施する駆動力制限手段とを有するものである。 Conventionally, there is known a technique of equipping a vehicle with an erroneous step response device in order to prevent the vehicle from suddenly starting due to an erroneous stepping operation in which the driver accidentally depresses the accelerator pedal. For example, the erroneous stepping response device described in Patent Document 1 has a erroneous stepping operation detecting means for detecting an erroneous stepping operation and a driving force limiting control which is a control for limiting the driving force when the erroneous stepping operation is detected. It has a driving force limiting means to be implemented.

本発明は、車両に誤踏み対応装置を装備することなく、ブレーキペダルを踏み易くしてアクセルペダルの誤踏みを防止するようにした車両用シートを提供することにある。 An object of the present invention is to provide a vehicle seat in which the brake pedal is easily stepped on to prevent the accelerator pedal from being erroneously stepped on, without equipping the vehicle with an erroneous stepping response device.

請求項１に係る発明は、運転席のシートクッションに対し、右側にアクセルペダルを配置し、該アクセルペダルの左側にブレーキペダルを配置してなる車両用シートであって、上記シートクッションの右側かつ前側部に、該シートクッションの他の部分よりも盛り上げられた土手部が設けられてなるようにしたものである。 The invention according to claim 1 is a vehicle seat in which an accelerator pedal is arranged on the right side of the driver's seat cushion and a brake pedal is arranged on the left side of the accelerator pedal, and is on the right side of the seat cushion. The front side portion is provided with a bank portion that is raised more than the other portion of the seat cushion.

特に高齢者等のドライバーは大腿部が外側に開く傾向がある。そのためアクセルペダルを踏む右脚がシートクッションに対する右側に向き易く、左側のブレーキペダルが自然に踏みにくくなる。又はとっさのブレーキ操作に対し踏み込んだ位置がアクセルペダルとなるおそれがある。 In particular, drivers such as the elderly tend to have their thighs open outward. Therefore, the right leg that steps on the accelerator pedal tends to face to the right with respect to the seat cushion, and the brake pedal on the left side naturally becomes difficult to step on. Alternatively, the accelerator pedal may be located at the position where the vehicle is depressed in response to a quick braking operation.

本発明では、シートクッションの右側かつ前側部に、該シートクッションの他の部分よりも盛り上げられた土手部が設けられる。これにより、土手部がドライバーの右足に左側への反力を与え、その右足により左側のブレーキペダルを踏み易くして、アクセルペダルの誤踏みを防止できる。 In the present invention, a bank portion that is raised more than other portions of the seat cushion is provided on the right side and the front side portion of the seat cushion. As a result, the bank portion gives the driver's right foot a reaction force to the left side, and the right foot makes it easier to step on the left brake pedal, so that the accelerator pedal can be prevented from being erroneously stepped on.

また、本発明では、土手部がシートクッションの右側かつ前側部に設けられ、該シートクッションの車両外側に臨む右側の前後方向に沿う全域に設けられるものでないため、ドライバーの乗降に支障を与えるものにもならない。 Further, in the present invention, the bank portion is provided on the right side and the front side portion of the seat cushion, and is not provided on the entire area along the front-rear direction on the right side of the seat cushion facing the outside of the vehicle, which hinders the driver's getting on and off. Not even.

尚、競技用バケットシートを除く通常のシートでは、シートクッションの左側縁部又は右側縁部が比較的フラットであり、右側縁部がドライバーの右足に左側への反力を与え、右足全体を左側に寄せる如くを期待することができない。 In normal seats other than competition bucket seats, the left or right edge of the seat cushion is relatively flat, and the right edge gives the driver's right foot a reaction force to the left, leaving the entire right foot on the left. I can't expect it to come close to me.

また、競技用バケットシートは、シートクッションの右側及び左側の前後方向に沿う全域に、ドライバーをサポートするための硬い土手部を設けており、乗降しづらい等、通常の使用性に困難を伴う。 In addition, the bucket seat for competition is provided with a hard bank portion for supporting the driver in the entire area along the front-rear direction on the right side and the left side of the seat cushion, which makes it difficult to get on and off, and is difficult to use normally.

本発明の車両用シート１０が適用される車両は、運転席のシートクッション１１に対し、右側にアクセルペダルを配置し、該アクセルペダルの左側にブレーキペダルを配置している。 In the vehicle to which the vehicle seat 10 of the present invention is applied, the accelerator pedal is arranged on the right side of the seat cushion 11 of the driver's seat, and the brake pedal is arranged on the left side of the accelerator pedal.

尚、本明細書において、車両の前方に向かって、右側を「右側」、左側を「左側」、前側を「前側」というものとする。 In the present specification, the right side is referred to as "right side", the left side is referred to as "left side", and the front side is referred to as "front side" when facing the front of the vehicle.

車両用シート１０は、図１乃至図３に示す如く、シートクッション１１の右側かつ前側部に、該シートクッション１１の他の部分よりも盛り上げられた土手部１２が設けられる。 As shown in FIGS. 1 to 3, the vehicle seat 10 is provided with a bank portion 12 raised on the right side and the front side portion of the seat cushion 11 more than the other portion of the seat cushion 11.

即ち、車両用シート１０は、シートクッション１１に着座したドライバーの右足１Ｒの大腿部が土手部１２に当接し、この土手部１２が右足１Ｒの大腿部に左側への反力を与え、右足１Ｒの全体を左側へ寄せることで、右足１Ｒによるブレーキ操作をサポートするものである。 That is, in the vehicle seat 10, the thigh portion of the driver's right foot 1R seated on the seat cushion 11 abuts on the bank portion 12, and the bank portion 12 applies a reaction force to the left side to the thigh portion of the right foot 1R. By moving the entire right foot 1R to the left side, the braking operation by the right foot 1R is supported.

このとき、車両用シート１０は、ドライバーの乗降性に配慮するため、土手部１２をドライバーの腰部横には設定せず、大腿部（足付根乃至膝）横に部分的に設定するものとする。 At this time, in order to allow the driver to get on and off the vehicle seat 10, the bank portion 12 is not set on the side of the driver's waist, but is partially set on the side of the thigh (foot base to knee). do.

尚、図３において、Ｃはシート中心を示し、１Ｒは右足を示し、１Ｌは左足を示す。Ｆは土手部１２が実線で示した右足１Ｒの大腿部に与える反力を示す。 In FIG. 3, C indicates the center of the seat, 1R indicates the right foot, and 1L indicates the left foot. F indicates the reaction force exerted by the bank portion 12 on the thigh portion of the right foot 1R shown by the solid line.

車両用シート１０のシートクッション１１に土手部１２を設ける具体的実施態様としては、シートクッション１１の右側かつ前側部に、ウレタンパッド等の適度な硬度とクッション性がある部材を配置し、シートクッション１１の他の部分よりも当該右側かつ前側のみ盛り上げた形状を設定する。 As a specific embodiment in which the bank portion 12 is provided on the seat cushion 11 of the vehicle seat 10, a member having appropriate hardness and cushioning property such as a urethane pad is arranged on the right side and the front side portion of the seat cushion 11 to provide a seat cushion. A shape is set in which only the right side and the front side of the other part of 11 are raised.

土手部１２を設けたシートクッション１１の形状は、クッションパッドそのもので形成しても良いし、クッションパッドにカバーパッドからなる土手部１２を被せても良い。既存の通常シートに対し、土手部１２を備えた後付けカバーパッドを設けても良い。 The shape of the seat cushion 11 provided with the bank portion 12 may be formed by the cushion pad itself, or the cushion pad may be covered with the bank portion 12 made of a cover pad. A retrofit cover pad provided with a bank portion 12 may be provided with respect to the existing normal sheet.

車両用シート１０は、図４、図５に示す如く、シートクッション１１に設けられる土手部１２における車両の前後方向において、図５（Ｂ）で示した前端部の車両内側形状を維持したまま、該前端部の車両外側形状をカットすることができる（カットラインＫ）。これにより、乗降時のドライバーの右足１Ｒが土手部１２に当たりにくくなり、乗降性を向上できる。 As shown in FIGS. 4 and 5, the vehicle seat 10 maintains the vehicle inner shape of the front end portion shown in FIG. 5B in the front-rear direction of the vehicle on the bank portion 12 provided on the seat cushion 11. The outer shape of the vehicle at the front end can be cut (cut line K). As a result, the driver's right foot 1R at the time of getting on and off is less likely to hit the bank portion 12, and getting on and off can be improved.

車両用シート１０にあっては、意匠性への配慮、又は左足１Ｌが車両のセンターコンソール側に寄ることを防ぐため、シートクッション１１の右側（車両外側）だけでなく左側（車両内側）にも一部盛り上がり形状を追加しても良い（左右対称性は不問）。 In the vehicle seat 10, in consideration of design or to prevent the left foot 1L from approaching the center console side of the vehicle, not only on the right side (outside the vehicle) but also on the left side (inside the vehicle) of the seat cushion 11. A partially raised shape may be added (regardless of left-right symmetry).

本実施形態によれば以下の作用効果を奏する。
本発明では、シートクッション１１の右側かつ前側部に、該シートクッション１１の他の部分よりも盛り上げられた土手部１２が設けられる。これにより、土手部１２がドライバーの右足１Ｒに左側への反力を与え、その右足により左側のブレーキペダルを踏み易くして、アクセルペダルの誤踏みを防止できる。 According to this embodiment, the following effects are exhibited.
In the present invention, a bank portion 12 that is raised more than other portions of the seat cushion 11 is provided on the right side and the front side portion of the seat cushion 11. As a result, the bank portion 12 applies a reaction force to the left side of the driver's right foot 1R, and the right foot makes it easier to step on the left brake pedal, so that the accelerator pedal can be prevented from being erroneously stepped on.

また、本発明では、土手部１２がシートクッション１１の右側かつ前側部に設けられ、該シートクッション１１の車両外側に臨む右側の前後方向に沿う全域に設けられるものでないため、ドライバーの乗降に支障を与えるものにもならない。 Further, in the present invention, the bank portion 12 is provided on the right side and the front side portion of the seat cushion 11, and is not provided on the entire area along the front-rear direction on the right side of the seat cushion 11 facing the outside of the vehicle, which hinders the driver from getting on and off. It does not give anything.

以上、本発明の実施例を図面により詳述したが、本発明の具体的な構成はこの実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。 Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like within a range that does not deviate from the gist of the present invention.
