Description

本発明は、車両のシートベルトと搭乗者との間に取り付けられて搭乗者を保護するための保護具に関するものである。 The present invention relates to a protective device attached between a vehicle seat belt and a occupant to protect the occupant.

例えば高齢者等を車椅子に乗せた状態で車両に搭乗させる場合、車椅子を車両の所定位置に固定させつつ搭乗者をシートベルトで保持させる必要がある。このシートベルトは、車椅子に乗る搭乗者の腹部を左右方向に亘って懸架するよう構成されているので、車両が急ブレーキした場合でも搭乗者が車椅子から飛び出してしまうのを回避可能とされているものの、その場合、搭乗者の腹部をシートベルトが強く圧迫してしまう可能性がある。 For example, when an elderly person or the like is to be boarded in a vehicle while being placed on a wheelchair, it is necessary to hold the occupant with a seat belt while fixing the wheelchair in a predetermined position of the vehicle. Since this seat belt is configured to suspend the abdomen of the occupant in the wheelchair in the left-right direction, it is possible to prevent the occupant from jumping out of the wheelchair even if the vehicle suddenly brakes. However, in that case, the seat belt may strongly press the passenger's abdomen.

そこで、従来、車椅子に乗った搭乗者と車両のシートベルトとの間に取り付けられて搭乗者を保護する保護具が提案されている（例えば、特許文献１参照）。かかる保護具は、ポリエチレン製の本体に複数本のひもが取り付けられており、搭乗者の腰部から腹部に亘って本体を巻き付けた状態としつつひもを結ぶことにより、搭乗者の胴回りに装着可能とされている。 Therefore, conventionally, a protective device that is attached between a passenger in a wheelchair and a seat belt of a vehicle to protect the passenger has been proposed (see, for example, Patent Document 1). This protective device has multiple strings attached to the polyethylene body, and can be worn around the passenger's waist by tying the strings while the body is wrapped around the occupant's waist and abdomen. Has been done.

次に、本実施形態に係る保護具１の使用方法について説明する。
先ず、固定具（不図示）により車椅子Ａを車両の床面Ｆに固定させるとともに、その車椅子Ａに乗る搭乗者Ｍの腹部に本体部２を密着させる。このとき、図９に示すように、本体部２の弧状を搭乗者Ｍの腹部に倣わせて密着させるとともに、シートベルトＳを固定部３に挿通して固定させる。 Next, a method of using the protective device 1 according to the present embodiment will be described.
First, the wheelchair A is fixed to the floor surface F of the vehicle by a fixture (not shown), and the main body 2 is brought into close contact with the abdomen of the passenger M who rides on the wheelchair A. At this time, as shown in FIG. 9, the arc shape of the main body portion 2 is brought into close contact with the abdomen of the passenger M, and the seat belt S is inserted into and fixed to the fixing portion 3.

このように、本実施形態によれば、搭乗者Ｍの腹部に密着可能とされるとともに、衝撃を吸収可能な衝撃吸収部材４を有した本体部２と、本体部２に形成され、シートベルトＳを当該本体部２に固定させ得る固定部３とを具備したので、搭乗者Ｍに対する装着を不要としつつシートベルトＳによる搭乗者Ｍの保持を確実に行わせることができる。すなわち、本体部２を搭乗者Ｍの腹部に密着させて取り付けるので、搭乗者Ｍに対するひも等による装着を不要とすることができるとともに、固定部３によりシートベルトＳを本体部２に固定させるので、保護具１に対してシートベルトＳがずれてしまうのを防止することができ、搭乗者Ｍの保持を確実に行わせることができるのである。 As described above, according to the present embodiment, the seat belt is formed on the main body 2 having the shock absorbing member 4 which can be brought into close contact with the abdomen of the passenger M and can absorb the shock, and the main body 2. Since the fixing portion 3 capable of fixing the S to the main body portion 2 is provided, it is possible to reliably hold the occupant M by the seatbelt S while eliminating the need to attach the S to the occupant M. That is, since the main body 2 is attached in close contact with the abdomen of the occupant M, it is not necessary to attach the seat belt to the occupant M with a string or the like, and the seat belt S is fixed to the main body 2 by the fixing portion 3. It is possible to prevent the seat belt S from being displaced with respect to the protective device 1, and it is possible to reliably hold the passenger M.

また、本実施形態に係る固定部３は、本体部２の表面側に一体形成されるとともに、シートベルトＳを挿通して固定可能とされたので、保護具１に対するシートベルトＳの固定を容易且つ円滑に行わせることができる。さらに、本実施形態に係る衝撃吸収部材４は、弾性特性が異なる発泡樹脂を複数層（第１層４ａ及び第２層４ｂ）に重ねて形成されるとともに、その表面側に硬質樹脂から成る成形部材５が取り付けられたので、所望の強度及び弾性特性の本体部２を得ることができる。 Further, since the fixing portion 3 according to the present embodiment is integrally formed on the surface side of the main body portion 2 and can be fixed by inserting the seat belt S, it is easy to fix the seat belt S to the protective tool 1. And it can be done smoothly. Further, the impact absorbing member 4 according to the present embodiment is formed by stacking foamed resins having different elastic properties on a plurality of layers (first layer 4a and second layer 4b), and is molded of a hard resin on the surface side thereof. Since the member 5 is attached, the main body portion 2 having desired strength and elastic characteristics can be obtained.

またさらに、本実施形態に係る成形部材５は、その中央上部に切り欠き部５ａが形成されたので、衝撃によって搭乗者Ｍの上半身が前方に倒れた際、搭乗者Ｍの腹部が切り欠き部５ａに収まることとなり、腹部に強い圧迫を受けるのを回避することができる。また、本実施形態に係る成形部材５は、その両縁下部に突出部（５ｂ、５ｂ）がそれぞれ形成されたので、搭乗者Ｍの骨盤の両側近傍を突出部（５ｂ、５ｂ）が押圧して座位保持が図られることとなり、左右方向の体の揺れを抑制することができる。 Further, since the molded member 5 according to the present embodiment has a notch portion 5a formed in the upper center thereof, when the upper body of the passenger M falls forward due to an impact, the abdomen of the passenger M is a notch portion. It fits in 5a, and it is possible to avoid receiving strong pressure on the abdomen. Further, since the molded member 5 according to the present embodiment has protrusions (5b, 5b) formed at the lower portions of both edges thereof, the protrusions (5b, 5b) press the vicinity of both sides of the pelvis of the occupant M. The sitting position is maintained, and it is possible to suppress the shaking of the body in the left-right direction.

加えて、本実施形態に適用されるシートベルトＳは、車椅子Ａに乗る搭乗者Ｍを保持して車両に固定し得るので、車椅子Ａに乗る搭乗者Ｍの保持を確実に行わせることができる。車椅子Ａは、図９に示すようなものに限らず、種々形態のものに適用することができ、例えば電動の車椅子であってもよい。 In addition, since the seatbelt S applied to the present embodiment can hold the passenger M in the wheelchair A and fix it to the vehicle, the passenger M in the wheelchair A can be surely held. .. The wheelchair A is not limited to the one shown in FIG. 9, and can be applied to various forms, for example, an electric wheelchair.

以上、本実施形態について説明したが、本発明はこれに限定されず、例えば固定部３を単なるループ状の部位としたものであってもよく、或いは他のファスナーを用いてシートベルトＳを固定するものとしてもよい。また、本実施形態においては、車椅子Ａに乗る人の腹部とシートベルトＳとの間に取り付けられた保護具１とされているが、車両のシートに取り付けられたベビーシート（横臥した乳児を保持するシート）やチャイルドシート（幼児が着座する着座面から成るシート）に適用するものであってもよい。さらに、車両のシートに直接着座した搭乗者Ｍの腹部に取り付けられて、搭乗者Ｍを保護する保護具に適用してもよい。 Although the present embodiment has been described above, the present invention is not limited to this, and for example, the fixing portion 3 may be a mere loop-shaped portion, or the seat belt S may be fixed by using another fastener. You may do it. Further, in the present embodiment, the protective device 1 is attached between the abdomen of the person in the wheelchair A and the seat belt S, but the baby seat (holding a lying baby) attached to the seat of the vehicle is used. It may be applied to a child seat (a seat consisting of a seating surface on which an infant sits) or a child seat. Further, it may be attached to the abdomen of the passenger M seated directly on the seat of the vehicle and applied to a protective device for protecting the passenger M.
