Description

安全气囊和车辆 技术领域
本发明涉及车辆中的安全装置，具体地，涉及安全气囊，以及，还涉及包括该安全气囊的车辆。
背景技术
现有的车辆中广泛采用安全气囊作为保护乘员的安全装置。安全气囊包括，例如，布置在方向盘中的安全气囊，布置在仪表盘中的安全气囊，以及，布置在车辆顶部的顶置式安全气囊。当车辆发生碰撞或受到冲击时，安全气囊的气体发生器便会接收到经由连接到气体发生器的线束传送来的信号，从而发生爆破。接着，爆破所产生的气体将使安全气囊的被折叠的气袋迅速充气，充气后的气袋发生膨胀，以保护乘员免受冲击所带来的伤害。
然而，碰撞期间，乘员的头部以及胸部可能滑动离开安全气囊的气袋，由此不再位于安全气囊的气袋的保护区域内，并且转而撞击到车辆内部的其他结构而受到伤害。因此，现有技术中的安全气囊难以确保碰撞期间乘员位于气袋的保护区域内，可靠性和安全性较低。
因此，期望一种具有较高的可靠性和安全性的安全气囊。
发明内容
本发明的目的是提供一种具有较高的可靠性和安全性的安全气囊。而且，本发明的安全气囊能够实现结构简单、制造成本低廉的目的。
本发明的一方面提供一种安全气囊，其包括：
气袋，其具有展开状态和收纳状态，并且包括主体部、连接到所述主体部两侧的第一侧翼和第二侧翼，当所述气袋处于展开状态时，所述第一侧翼和所述第二侧翼从所述主体部朝向乘客延伸，以使乘客的头部容纳在 所述第一侧翼和所述第二侧翼之间的凹陷部中；
所述第一侧翼包括第一内侧面和第一外侧面，所述第二侧翼包括第二内侧面和第二外侧面，并且，所述第一内侧面和所述第二内侧面彼此相邻的边缘连接在一起，当所述气袋处于展开状态时，所述第一内侧面和所述第二内侧面用于限定所述第一侧翼和所述第二侧翼之间的所述凹陷部。
根据本发明的实施例，所述第一侧翼和所述第二侧翼被构造为彼此相同，并且与所述主体部流体连通。

根据本发明的实施例，当处于展开状态时，所述主体部包括与所述第一侧翼和所述第二侧翼两者相对的前侧面，并且，用于对所述气袋进行充气的气体发生器设置在所述前侧面处。
根据本发明的实施例，还包括拉带，所述拉带的一端被构造为连接到所述前侧面处，并且所述拉带的另一端被构造为连接到所述主体部的靠近所述凹陷部的部分处。
根据本发明的实施例，所述主体部的至少一部分、所述第一侧翼和所述第二侧翼被构造为由同一片织物制造。
根据本发明的实施例，所述同一片织物被构造为，在展开状态下时，包括矩形第一部段和位于所述第一部段的第一侧边上的两个三角形第二部段，所述第一部段用于形成所述主体部，两个所述第二部段分别用于形成所述第一侧翼和所述第二侧翼。
根据本发明的实施例，所述前侧面被构造为连接到所述同一片织物的与所述第一侧边相对的第二侧边上。

附图说明
图1示出根据本发明实施例的安全气囊。
图2示出用于制造根据本发明实施例的安全气囊的方法。
具体实施方式
以下将结合附图描述根据本发明的安全气囊和车辆的具体实施方式。下面的详细描述和附图用于示例性地说明本发明的原理，本发明不限于所描述的优选实施例，本发明的保护范围由权利要求书限定。
需要说明的是，本发明的安全气囊适用于车辆中。作为示例，本发明的安全气囊可以安装在车辆的仪表盘中。
图1示出根据本发明实施例的安全气囊。以下参照图1描述根据本发明实施例的安全气囊。
如图1所示，根据本发明实施例的安全气囊包括气袋10和气体发生器(未示出)。气袋10具有展开状态和收纳状态，以及，气体发生器用于对气袋10充气以使气袋10膨胀而进入展开状态。为了清楚地看到气袋10的结构，图1中示出的气袋10处于展开状态，并且，图1中示出的气袋10在使用时其左侧将面对乘员。
继续参照图1，能够从图1中示出的处于展开状态下的气袋10观察到，气袋10包括主体部100、连接到主体部100两侧的第一侧翼200和第二侧翼300，主体部100包括与第一侧翼200和第二侧翼300两者相对的前侧面400，即，第一侧翼200和第二侧翼300两者均位于主体部100的左侧，前侧面400位于主体部100的右侧。并且，用于对气袋10进行充气的气体发生器可以设置在前侧面400处。当气袋10如图1所示处于展开状态时，第一侧翼200和第二侧翼300从主体部100朝向乘客延伸，以使乘客的头部容纳在第一侧翼200和第二侧翼300之间的凹陷部500中。进一步地，第一侧翼200包括第一内侧面200A和第一外侧面200B，第二侧翼300包括第二内侧面300A和第二外侧面300B，并且，第一内侧面200A和第二内侧面300A彼此相邻的边缘连接在一起，当气袋10处于展开状态时，第 一内侧面200A和第二内侧面300A用于限定第一侧翼200和第二侧翼300之间的凹陷部500。此外，第一侧翼200和第二侧翼300被构造为，当处于展开状态下，在远离主体部100的方向上逐渐收窄而分别形成第一凸角和第二凸角。
当以上安全气囊安装在例如仪表盘中对前排乘客进行保护时，在发生碰撞事件之前，乘员的头部基本与车辆同步运动；在碰撞事件期间，车辆的行进方向和速度可能剧烈而突然地改变。当这种碰撞触发安全气囊展开气袋时，气袋在车辆的特定方向上加速，也就是说，从仪表盘向后展开。由于碰撞事件本身已经改变了车辆的行驶方向，所以即使受到现代三点式安全带的限制，乘员也可能不再与车辆同步运动。此外，乘员冲击安全气囊的气袋时可能受到某种程度的损伤。例如，乘员的头部可能由于冲击安全气囊的气袋而相对于脊柱旋转加速。这种旋转加速度或减速度可能对乘员造成伤害。换句话说，当乘员冲击安全气囊的气袋时，乘员的头部可能发生显著的旋转或扭转，这可能会引起伤害。例如，当前排乘客在碰撞事件期间向前方向移动并撞击安全气囊的气袋时，乘员的头部可能以相当大的力绕头部的纵轴旋转。因此，需要安全气囊在碰撞事件期间具有降低乘员头部旋转速度的功能，以降低乘员头部快速旋转造成的创伤性头部/脑部损伤风险。本发明的安全气囊具有上述功能，这将在下文进行详细介绍。
如图1所示，在本发明的安全气囊的气袋10中，在凹陷部500内产生低织物张力区域和高织物张力区域。具体地，低织物张力区域位于气袋10的第一内侧面200A和第二内侧面300A彼此相邻的边缘处，以及，高织物张力区域位于第一侧翼200和第二侧翼300两者远离主体部100的部分(例如，凸角的尖端部分)处。低织物张力区域可以减小气袋10引起乘员的头部旋转的可能性。高织物张力区域提供支撑，以防止或限制乘员冲出第一侧翼200或第二侧翼300。因此，在本发明的安全气囊中，第一侧翼和第二侧翼之间形成的凹陷部可以接纳乘员的头部，并且向头部侧面提供支撑，以抵消头部上的可能导致头部在围绕头部的纵轴顺时针或逆时针旋转的力。
因此，本发明的安全气囊能够确保碰撞期间乘员位于气袋的保护区域 内，并且能够降低乘员头部快速旋转造成的创伤性头部/脑部损伤风险，由此具有较高的可靠性和安全性。与此同时，在本发明的安全气囊中，气袋通过从主体部两侧延伸的两个侧翼形成凹陷部，以实现碰撞期间保护乘员头部的目的，因此，本发明的安全气囊还具有结构简单，制造成本低廉的特点。
图2示出用于制造根据本发明实施例的安全气囊的方法。以下参照图2描述根据本发明实施例的安全气囊的制造方法。需要说明的是，图1中示出的安全气囊的气袋10可以使用参照图2描述的制造方法进行制造，但是，图1中示出的安全气囊的气袋10并非被限制为以下参照图2描述的制造方法制造出来的气袋。
如图2所示，提供三片织物，即，第一片织物W1，第二片织物W2和第三片织物W3。展开状态下的第一片织物W1被构造为包括矩形第一部段120和位于第一部段120的第一侧边(即，上侧边)上的两个三角形第二部段210和310，其中，第一部段120用于形成主体部的一部分，两个第二部段210和310分别用于形成第一侧翼和第二侧翼。而且，在展开状态下的第一片织物W1被构造为包括位于第一部段的第二侧边上的两个三角形第三部段，第三部段被构造为与前侧面连接。此外，第二片织物W2被构造为用于形成前侧面，前侧面被构造为连接到第一片织物W1的与第一侧边(即，上侧边)相对的第二侧边(即，下侧边)上；以及，第三片织物W3被构造为用于形成拉带。
本发明的安全气囊的气袋的制造方法如下：
在第一片织物W1的上侧边标记A1、A2、A3、B1、B2、B3共六个特征点，其中，A3点和B1点重合；
在第一片织物W1的下侧边标记C1、C2、C3、C4、C5共五个特征点；
在第二片织物W2上标记D1、D2、D3、D4共四个特征点；
使点A1和点A3重合，将边线A1A2和边线A2A3对折连接(例如，缝合或粘接)在一起；
使点B1和点B3重合，将边线B1B2和边线B2B3对折连接(例如，缝合或粘接)在一起；
将第三片织物W3的一端连接到主体部的靠近凹陷部的部分处；
将边线A1C1和边线B3C5对折连接(例如，缝合或粘接)在一起；
将曲线C1C2C3和曲线D1D2D3连接(例如，缝合或粘接)在一起，将第三片织物W3的另一端连接到前侧面处，以及，将曲线C3C4C5和曲线D1D4D3连接(例如，缝合或粘接)在一起。
需要说明的是，以上描述的用于制造本发明的安全气囊的气袋的制造方法仅仅是示例，本领域技术人员可以根据实际情况对以上方法的各个步骤的顺序进行调整甚至删减。
作为本发明的一个优选实施例，第一侧翼和第二侧翼被构造为彼此相同，并且与主体部流体连通。该优选实施例具有结构简单、易于制造的特点，但是这仅仅是示例，本发明的安全气囊不限于此，例如，本领域技术人员可以根据实际情况将第一侧翼和第二侧翼设置为彼此不相同，和/或，第一侧翼与第二侧翼中的至少一者设置为不与主体部流体连通，相应地，为与主体部不流体连通的第一侧翼和第二侧翼中的至少一者设置单独的气体发生器。
作为本发明的一个优选实施例，气袋包括拉带，拉带的一端被构造为连接到前侧面处，并且拉带的另一端被构造为连接到主体部的靠近凹陷部的部分处。该实施例能够通过拉带更好地控制气袋的厚度和形状，但是这仅仅是示例，本发明的安全气囊不限于此，例如，本领域技术人员可以根据实际情况不设置拉带。
根据本发明的一个优选实施例，主体部的至少一部分、第一侧翼和第二侧翼被构造为由同一片织物制造。该实施例具有制造成本低廉且结构简单的特点，但是这仅仅是示例，本发明的安全气囊不限于此，例如，本领域技术人员可以根据实际情况选择织物的片数。此外，本发明的安全气囊中，气袋不限于包括前侧面，例如，本领域技术人员可以根据实际情况，将主体部的制造方法更改为，将图2中所示的的第一片织物W1的曲线C1C2C3和曲线C3C4C5连接(例如，缝合或粘接)在一起。
如前，尽管说明中已经参考附图对本发明的示例性实施例进行了说明，但是本发明不限于上述具体实施方式，本发明的保护范围应当由权利要求 书及其等同含义来限定。
